A free and popular virtualization tool

VirtualBox is free, enterprise-ready virtualization software for Windows users. Developed by the Oracle Corporation, the tool lets users run different operating systems on their computers. It’s a feature-rich product and is one of the only professional virtualization tools available as open-source software. It’s updated regularly by its community of users, and Oracle ensures that the released product meets professional standards. VirtualBox is quite popular and also available for download on devices running macOS.

Increase agility and reduce hardware costs

Nowadays, virtual machines are becoming an integral part of businesses as well as cloud computing solutions. With VirtualBox, users can harness the power of virtualization from their home computers. With VirtualBox, you can create a representation of an operating system that significantly reduces hardware costs while boosting agility and efficiency.

What is VirtualBox used for?

When you download VirtualBox for Windows, you can easily run Mac and Linux operating systems on your native Windows device. Additionally, you can use the tool to run applications you would otherwise not have access to. It also offers all the features that make virtualization attractive.

Users can run an old operating system like Windows 8 on their Windows 10 device, or test an OS before installing it fully. They can even use the full performance of their desktops by packing multiple virtual machines onto a few hosts while saving up on a lot of hardware costs. Owing to the snapshot feature, users can easily switch to an old snapshot and avoid frequent backups whenever something goes wrong.

Easy to install for tech-savvy users

Installing VirtualBox and another operating system is quite easy if you’re technologically savvy. In case you’re inexperienced, you may have to go through the manual provided by Oracle. The installation only takes about 5 minutes on a computer with 2GB RAM. You can choose to either install the software or add support for USB and different types of networking, including host-only, bridge, and conventional. Once installed, the software offers a great user experience so you can run different operating systems and applications from your native PC environment.

Simple and easy-to-use interface

VirtualBox has a clean interface with three primary menus, which include Machine, File, and Help. You can use the Machine option to create your first guest operating system. Adding a virtual machine is as easy as pressing CTRL and N together. Once you do that, a module pops up and asks you to choose the type of operating system you want to load as well as its unique name. The latest version of the software allows you to scale the display, so you can reduce the size of the window and still make out everything.

The File option gives users access to the media manager, preference module, as well as import and export features. With VirtualBox, you can reduce or limit the CPU and IO time of any virtual machine that you’re running. By setting a limit, you can ensure that the virtual OS doesn’t drain your system resources. Apart from this, the software also offers various tools to fix bugs and increase the performance of your virtual machines.

Multiple customization options

VirtualBox supports numerous operating systems including Linux, macOS, and Oracle Solaris hosts. It provides users with the option to create a multi-platform or collated server, useful for testing and development. You can even use different customization options to personalize the user interface of the guest OS.

Integration may take a while

One of the biggest challenges of running the free version of VirtualBox is creating a guest operating system. Users don’t have the option to automate certain features and have to go at it manually. The process also requires patience on the part of the users. For instance, if you wanted to install Windows 10 or even Windows 7 using VirtualBox, adding the final touches would take time.

Fortunately, the software offers different guided modes, so users have some help when they need it. VirtualBox doesn’t offer a deep integration option, which is quite an advantage if you’re concerned about privacy. This means that if a virtual machine is vulnerable to a virus attack, the host system isn't compromised. While paid software offers much better integration between the host and guest OS, VirtualBox offers all the necessary tools needed for virtualization.

Offers exhaustive documentation

VirtualBox is open-source software, which means that it has a vast online community. Typical to all such software programs, these communities create a wide range of information and help. Users of the software get easy access to technical documents, changelog, operation manuals, FAQs, and more. There also exists a Bug Tracker page, where users can report bugs and track any status updates. Apart from an array of information, Oracle also offers live chat, so users can easily connect with a representative for any questions.

Is VirtualBox free?

Formerly known as Sun VirtualBox, the base package of the virtualization tool is free to download and use. It is licensed under the GNU General Public License and is available as open-source software. While the base pack is free, Oracle also provides an extension pack with added features. Since it falls under the Personal Use and Evaluation License, corporate users need to purchase a commercial license from Oracle.

Is VirtualBox secure?

VirtualBox is completely safe to download and use. The software offers added security in terms of protection from malware. A key advantage of using VirtualBox is that it is quite secure. Malware doesn’t function properly in a virtualized environment. A virus usually shuts down the moment it detects a virtual environment. By using VirtualBox, you can protect your hard drive from viruses, test new operating systems, and run applications that are incompatible with your existing OS.

VirtualBox has some alternatives

While VirtualBox is one of the most prominent open-source virtualization software, it does have some competitors. If you’re looking for other virtualization tools, you can check out VMware Workstation Pro, Virtual PC, and VMware Workstation Player.

Which is better - VMware or VirtualBox?

Unless you’re looking for a virtualization software for company work, you should go with VirtualBox. Though VMware offers better drag-and-drop functions between guest and host as well as a better interface, it is limited in the snapshot feature. VirtualBox, on the other hand, offers unlimited snapshots - a feature that is only available in the premium version of VMware.

Should I download VirtualBox?

If you’re looking to run applications that aren’t compatible with your system or want to test other operating systems, you should download VirtualBox. It’s a free, open-source solution that comes with all the features of enterprise-ready programs. While it may take time during the primary integration, it does run well after the process is complete.

Once a guest operating system is installed, you can easily access and work on it without any hassle. It also comes with an easy-to-use interface that even novice users can command after they’ve gone through the user manual. Moreover, since the tool is monitored by Oracle, users have access to a wide range of documentation and help.

How to Install macOS Sierra 10.12 on VirtualBox?

In our previous post, we have shown you how to install macOS Sierra 10.12 on VMware, and now in this article, I’m going to show you how to install macOS Sierra 10.12 on VirtualBox on Windows 10. Apple has announced the next version of its Mac operating system “macOS Sierra”. Of course, the real change is that, after fifteen years, Apple has finally ditched the “OS X” moniker. All things old are new again, and the new operating system will only call “macOS.” So, I’m not going to discuss anymore regarding Apple’s new release “macOS Sierra” instead; I’m going to walk you through installing macOS Sierra on VirtualBox on Windows operating system.

Update: Before we get started, let me mention that several versions of macOS have come out since macOS Sierra and we have already created a step by step guides to install them on VMware or VirtualBox. So if you want to install the newer versions of macOS then please check out the links below:

A free and popular virtualization tool

VirtualBox is free, enterprise-ready virtualization software for Windows users. Developed by the Oracle Corporation, the tool lets users run different operating systems on their computers. It’s a feature-rich product and is one of the only professional virtualization tools available as open-source software. It’s updated regularly by its community of users, and Oracle ensures that the released product meets professional standards. VirtualBox is graphisoft archicad popular and also available for download on devices running macOS.

Increase agility and reduce hardware costs

Nowadays, virtual machines are becoming an integral part of businesses as well as cloud computing solutions. With VirtualBox, users can harness the power of virtualization from their home computers. With VirtualBox, you can create a representation of an operating system that significantly reduces hardware costs while boosting agility and efficiency.

What is VirtualBox used for?

When you download VirtualBox for Windows, you can easily run Mac and Linux operating systems on your native Windows device. Additionally, you can use the tool to run applications you would otherwise not have access to. It also offers all the features that make virtualization attractive.

Users can run an old operating system like Windows 8 on their Windows 10 device, or test an OS before installing it fully. They can even use the full performance of their desktops by packing multiple virtual machines onto a few hosts while saving up on a lot of hardware costs. Owing to the snapshot feature, users can easily switch to an old snapshot and avoid frequent backups whenever something goes wrong.

Easy to install for tech-savvy users

Installing VirtualBox and another operating system is quite easy if you’re technologically savvy. In case you’re inexperienced, you may have to go through the manual provided by Oracle. The installation only takes about 5 minutes on a computer with 2GB RAM. You can choose to either install the software or add support for USB and different types of networking, including host-only, bridge, and conventional. Once installed, the software offers a great user experience so you can run different operating systems and applications from your native PC environment.

Simple sound forge audio studio 13 review - Crack Key For U easy-to-use interface

VirtualBox has a clean interface with three primary menus, which include Machine, File, and Help. You can use the Machine option to create your first guest operating system. Adding a virtual machine is as easy as pressing CTRL and N together. Once you do that, a module pops up and asks you to choose the type of operating system you want to load as well as its unique name. The latest version of the software allows you to scale the display, so you can reduce the size of the window and still make out everything.

The File option gives users access to the media manager, preference module, as well as import and export features. With VirtualBox, you can reduce or limit the CPU and IO time of any virtual machine that you’re running. By setting a limit, you can ensure that the virtual OS doesn’t drain your system resources. Apart from this, the software also offers various tools to fix bugs and increase the performance of your virtual machines.

Multiple customization options

VirtualBox supports numerous operating systems including Linux, macOS, and Oracle Solaris hosts. It provides users with the option to create a multi-platform or collated server, useful for testing and development. You can even use different customization options to personalize the user interface of the guest OS.

Integration may take a while

One of the biggest challenges of running the free version of VirtualBox is creating a guest operating system. Users don’t have the option to automate certain features and have to go at it manually. The process also requires patience on the part of the users. For instance, if you wanted to install Windows 10 or even Windows 7 using VirtualBox, adding the final touches would take time.

Fortunately, the software offers DeskSoft SmartCapture 3.17 Features guided modes, so users have some help when they need it. VirtualBox doesn’t offer a deep integration option, which is quite an advantage if you’re concerned about privacy. This means that if a virtual machine is vulnerable to a virus attack, the host system isn't compromised. While virtualbox 64 bit crack download - Crack Key For U software offers much better integration between the host and guest OS, VirtualBox offers all the necessary tools needed for virtualization.

Offers exhaustive documentation

VirtualBox is open-source software, which means that it has a vast online community. Typical to all such software programs, these communities create a wide range of information and help. Users of the software get easy access to technical documents, changelog, operation manuals, FAQs, and more. There also exists a Bug Tracker page, where users can report bugs and track any status updates. Apart from an array of information, Oracle also offers live chat, so users can easily connect with a representative for any questions.

Is VirtualBox free?

Formerly known as Sun VirtualBox, the base package of the virtualization tool is free to download and use. It is licensed under the GNU General Public License and is available as open-source software. While the base pack is free, Oracle also provides an extension pack with added features. Since it falls under the Personal Use and Evaluation License, corporate users need to purchase a commercial license from Oracle.

Is VirtualBox secure?

VirtualBox is completely safe to download and use. The software offers added security in terms of protection from malware. A key advantage of using VirtualBox is that it is quite secure. Malware doesn’t function properly in a virtualized environment. A virus usually shuts down the moment it detects a virtual environment. By using VirtualBox, you can protect your hard drive from viruses, test new operating systems, and run applications that are incompatible with your existing OS.

VirtualBox has some alternatives

While VirtualBox is one of the most prominent open-source virtualization software, it does have some competitors. If you’re looking for other virtualization tools, you can check out VMware Workstation Pro, Virtual PC, and VMware Workstation Player.

Which is better - VMware or VirtualBox?

Unless you’re looking for a virtualization software for company work, you should go with VirtualBox. Though VMware offers better drag-and-drop functions between guest and host as well as a better interface, it is limited in the snapshot feature. VirtualBox, on the other hand, offers unlimited snapshots - a feature that is only available in the premium version of VMware.

Should I download VirtualBox?

If you’re looking to run applications that aren’t compatible with your system or want to test other operating systems, you should download VirtualBox. It’s a free, open-source solution that comes with all the features of enterprise-ready programs. While it may take time during the primary integration, it does run well after the process is complete.

Once a guest operating system is installed, you can easily access and work on it without any hassle. It also comes with an easy-to-use interface that even novice users can command after they’ve gone through the user manual. Moreover, since the tool is monitored by Oracle, users have access to a wide range of documentation and help.

To download the RHEL 8 ISO image at no cost at all, head over the Red Hat developer program and create an account. Fill in all the required details.

Create RedHat Account

Once done, proceed over to the Red Hat Login page to complete your profile by providing other details such as your local address.

Thereafter, head out to the RHEL 8 download page and download the RHEL 8 ISO file for free. Once you have downloaded the ISO image, you can choose to create a bootable USB drive using Rufus or any other utility of your choice.

If you wish to install RHEL 8 on VirtualBox as I’ll demonstrate, an ISO image alone is enough.

Installing RHEL 8 on VirtualBox

1. Open your VirtualBox and click on the “New” icon. Assign a preferred name to your virtual machine and click “Next”.

Create New Virtual Machine

2. In the next step, allocate some memory for your virtual machine. In this case, I have chosen to assign a memory capacity of 2048 MB.

This will form the basis for a second tutorial that will walk through installing and configuring Ruby on Rails on an Ubuntu server.

    Let’s get started!

    What Is VirtualBox?

    VirtualBox is a software virtualization package that you can install on your operating system (just as you would a normal program). It supports the creation and management of virtual machines into which you can install a second operating system.

    In VirtualBox terminology, the operating system on which you install VirtualBox (i.e. your regular OS) is called the host. The operating system you install within VirtualBox (i.e. inside the virtual machine) is called the guest.

    For this tutorial, I’ll be using Linux Mint 19.2 as the host OS, but there’s no reason you couldn’t use a different Linux distro, or macOS, or Windows (if you’re so inclined).

    Install VirtualBox

    The first thing to do is to get VirtualBox installed. I’ll not go into much detail here, as there are comprehensive instructions for all of the main operating systems on the project’s homepage.

    Personally, I downloaded and installed the deb package for Ubuntu 18.04 / 18.10 / 19.04. This is because the VirtualBox version in the Mint repos is slightly outdated and I wanted to be running the latest version.

    Download Ubuntu Server

    The next thing to do is to grab a copy of Ubuntu Server. You can do this from their download page. This will download a 889MB iso file to your PC.

    At the time of writing the current LTS version is Ubuntu Server 18.04.3 and this is what I’ll be using. It’s supported until April 2023 and is available as 64-bit only.

    Create a New Virtual Machine

    Start up VirtualBox. This should open the VirtualBox Manager, the interface from which you will administer all of your virtual machines.

    Welcome to VirtualBox

    Next Click on New (in the top right of the VirtualBox Manager), give your virtual machine a name and the two drop down menus should automatically update.

    Name and operating system

    Click Next. The wizard will now ask you to select the amount of memory (RAM) in megabytes to be allocated to the virtual machine. I chose 2GB (2048 megabytes).

    Memory size

    Click Next and you will be prompted to add a virtual hard disk to the new machine. Make sure that Create a virtual hard disk now is selected, then press Create.

    Hard disk

    Now we need to choose the file type for the new virtual hard disk. Make sure that VDI (VirtualBox Disk Image) is checked and press Next.

    Hard disk file type

    On the next screen you will be asked whether the new virtual hard disk should grow as it is used (dynamically allocated) or if it should be created at its maximum size. Make sure that dynamically allocated is selected, then click Next.

    Storage on physical hard disk

    Finally, select the size of the virtual hard disk in megabytes. The default size of 10GB should be plenty, but feel free to increase this as you see fit. Then click Create.

    File location and size

    The hard disk should now be created and after a short while you should find yourself back in the VirtualBox Manager. You should be able to see your newly created virtual machine listed on the left.

    Install Ubuntu Server in the Virtual Machine

    Make sure your virtual machine is selected and press Start. VirtualBox Manager will ask you to select a virtual optical disk file or a physical optical drive to start the virtual machine from. Select the iso file you downloaded previously and press Start.

    Select start-up disk

    The Ubuntu installation process will now begin. It consists of thirteen steps and is quite painless.

    The Welcome Screen

    Here you should select your preferred language. I’m using English.

    The Welcome Screen

    The Keyboard Configuration Screen

    Here you should select a keyboard layout. As I’m using a German keyboard, I asked Ubuntu to detect my layout, which it did with a couple of simple questions.

    The Keyboard Configuration Screen

    The Network Connections Screen

    Here Ubuntu will attempt to configure the standard network interface. Normally you can just accept the default and select Done.

    The Network Connections Screen

    The Configure Proxy Screen

    If your system requires a proxy to connect to the internet (mine doesn’t), enter its details in the next dialogue. Then select Done.

    The Configure Proxy Screen

    The Ubuntu Archive Mirror Screen

    If you wish to use an alternative mirror for Ubuntu, you can enter the details here. Otherwise accept the default mirror by selecting Done.

    The Ubuntu Archive Mirror Screen

    The Filesystem Setup Screen

    The installer can guide you through partitioning an entire disk or, if you prefer, you can do it manually. If you choose to partition an entire disk you will still have a chance to review and modify the results before Ubuntu is installed. I selected Use An Entire Disk.

    I was then prompted to select my virtual machine’s hard disk as the disk to install to, before being shown a summary of what the installer would do. As this is a “destructive action”. I was asked to confirm my choice with Continue.

    The Filesystem Setup Screen

    The Profile Setup Screen

    Here you are required to enter:

    • Your (real) name
    • Your server’s name
    • Your username
    • Password

    Fill these details out as you see fit.

    The Profile Setup Screen

    The SSH Setup Screen

    Here we have a chance to install the OpenSSH server package. We’ll need this to connect to the virtual machine via SSH later on, so ensure that you select it.

    You also have the opportunity to import your SSH keys from GitHub or Launchpad. I selected No for this option.

    The SSH Setup Screen

    The Featured Server Snaps screen

    Here you can select from a list of popular snaps to install on your system. Snaps are self-contained software packages that work across a range of Linux distributions. I didn’t select any.

    The Featured Server Snaps screen

    And that’s it, the installation is complete. Ubuntu will ask you to remove the installation medium (which you can do via Devices > Optical Drives > Remove disk from virtual drive > Force unmount) and then reboot.

    If this option is virtualbox 64 bit crack download - Crack Key For U out, you’re good to go. Just reboot.

    Up and Running with SSH

    Once your virtual machine has rebooted and you have logged in, you’ll probably notice that some packages can be updated.

    Let’s fix that:

    Now let’s double check that SSH is installed (it should be if you selected the option Install OpenSSH server during instalation).

    If you get a “command not found” error, you can install it with:

    The next step is to give our Virtualbox 64 bit crack download - Crack Key For U server an IP address on our local network. To do this, power off dvdfab 11 crack - Activators Patch virtual machine using or Machine > ACPI Shutdown.

    Then, in VirtualBox Manager, click on the Network panel on the right. Change the setting Adapter 1 > Attached to to “Bridged Adapter” and click OK.

    VirtualBox Manager - Network Adapter 1

    Start up your virtual machine, then enter (in the guest) and note the IP address assigned to your main network adapter. In my case this was .

    Note: it is also possible to stick with the original NAT interface and SSH into the guest using port forwarding. You can read more about that here. You can find information on all of the VBox network settings in this comprehensive guide.

    Starting and Stopping VirtualBox in Headless Mode

    You might have noticed, working with the VirtualBox Manager and the guest OS is a bit of a pain. If you’re going to continue doing this, you should at least install the guest additions, as well as enable clipboard support.

    There is a slightly nicer way however — you can start and stop the virtual machine using the VBoxManage command from your terminal.

    To power on:

    And to power off:

    Where “Ubuntu Server 18.04.3” is whatever you called your virtual machine (the name it has in the VirtualBox Manager GUI).

    Connecting to the Ubuntu Server

    Let’s go ahead and start the Ubuntu server in headless mode, before connecting to it via SSH.

    Note: The following commands should be run on your host.

    On most *nix systems, the SSH client software should be part of the default installation. If you don’t have it available, you should be able to grab it from the repos, like so:

    or just hit DuckDuckGo.

    Then (ensuring that you Athentech Perfectly Clear Complete 3.11.2.1915 Crack License Key - Activators Patch “jim” and the IP address with your corresponding values) you can connect like so:

    This will give you a warning that the host’s authenticity cannot be established and ask you if you want to continue connecting. Answer “yes”.

    Next, it will prompt you for your password. Enter it and you will be connected to your Ubuntu server from your host OS.

    Connected to the Ubuntu server via SSH

    For Windows Users

    If you’re running Windows you’ll need to install a SSH client such as PuTTY.

    When PuTTY starts, a window titled PuTTY Configuration should open. This window has a configuration pane on the left, a Host Name field and other options in the middle, and a pane for saving session profiles in the lower right area.

    For simple use, all you need to do is to enter the IP address of the host you want to connect to in the Host Name field and click Open.

    PuTTY Configuration

    Generate and Install a SSH Key Pair

    SSH keys offer a virtualbox 64 bit crack download - Crack Key For U manner of logging into a server without the need of a password.

    In a nutshell, this depends upon you generating a public and a private SSH key pair. The private key is kept on your PC (and should be guarded carefully). The public key is copied over to the server you wish to connect to.

    SSH keys are a complex subject and as such, out of the scope of this tutorial. If you’d like to find out more, I recommend looking for a dedicated tutorial (such as this one).

    Generate the Keys

    On *nix systems (Windows users see the next section), you can generate your key pair with the following command:

    The option Visual Studio 2021 Crack Download Free Version [Product Key Free] ssh-keygen to store the private key in the new OpenSSH format instead of the old (and more compatible PEM format). This is advisable, as the new OpenSSH format has an increased resistance to brute-force password cracking.

    The option is used to set the key length to 4096 bits instead of the default 1024 bits for security reasons.

    In the following dialogue you will be required to answer a couple of questions:

    • Where to save the newly generated key pair
    • Which passphrase to use

    Here you can accept the default location and leave the passphrase blank by pressing .

    ssh-keygen will then output a summary of what it has done:

    Copy the Public Key to the Ubuntu Server

    To copy the public key to the Ubuntu server use:

    Where is the path to your public key, taken from the output above. And where should be altered to reflect your details.

    The command will run and you should be asked for your server password. Enter it, then attempt to log into the server like so:

    This time you should be in without a password.

    For Windows Users

    You should be able to use a tool like PuTTYgen to achieve the same thing. Here is a tutorial on using PuTTYgen to create a new key pair for authentication.

    You will have a little more leg work when it comes to copying the key to the sound forge audio studio 13 review - Crack Key For U, where you will need to add the public key to a file.

    You can do that like so:

    This will create the appropriate file, then open the nano editor into which you can copy your newly generated public key.

    When you’re done, press + to save your changes and exit nano.

    Conclusion

    This has been quite a long post, but by the end of it you should have a working installation of Ubuntu Server running on VirtualBox that you can connect to from your host operating system via SSH.

    As mentioned, this will form the basis for a future tutorial on deploying a Ruby on Rails app to an Ubuntu server.

    If you have any questions or feedback, I’d be glad to hear your from you in the comments.

    How to Install macOS Sierra 10.12 on VirtualBox?

    In our previous post, we have shown you how to install macOS Sierra 10.12 on VMware, and now in this article, I’m going to show you how to install macOS Sierra 10.12 on VirtualBox on Windows 10. Apple has announced the next version of its Mac operating system “macOS Sierra”. Of course, the real change is that, after fifteen years, Apple has finally ditched the “OS X” moniker. All things old are new again, and the new operating system will only call “macOS.” So, I’m not going to discuss anymore regarding Apple’s new release “macOS Sierra” instead; I’m going to walk you through installing macOS Sierra on VirtualBox on Windows operating system.

    Update: Before we get started, let me mention that several versions of macOS have come out since macOS Sierra and we have already created a step by step guides to install them on VMware or VirtualBox. So if you want to install the newer versions of macOS then please check out the links below:

    System Requirements

    Before we start, make sure to read the following requirements. Please do not skip this step because it’ll help you to successfully install macOS Sierra on VirtualBox on Windows 10 PC.

    How to Install macOS Sierra 10.12 on VirtualBox?

    In our previous post, we have shown you how to install macOS Sierra 10.12 on VMware, and now in this article, I’m going to show you how to install macOS Sierra 10.12 on VirtualBox on Windows 10. Apple has announced the next version of its Mac operating system “macOS Sierra”. Of course, the real change is that, after fifteen years, Apple has finally ditched the “OS X” moniker. All things old are new again, and the new operating system will only call “macOS.” So, I’m not going to discuss anymore regarding Apple’s new release “macOS Sierra” instead; I’m going to walk you through installing macOS Sierra on VirtualBox on Windows operating system.

    Update: Before we get started, let me mention that several versions of macOS have come out since macOS Sierra and we have already created a step by step guides to install them on VMware or VirtualBox. So if you want to install the newer versions of macOS then please check out the links below:

    System Requirements

    Before we start, make sure to read the following requirements. Please do not skip this step because it’ll help you to successfully install macOS Sierra on VirtualBox on Windows 10 PC.

    • Minimum 2 GB memory (Recommended 8GB or higher)
    • Minimum 2 cores of processors (Recommended 4 cores or higher)
    • Hard disk free space 20 GB (Recommended 100GB or higher)
    • Your system should support Intel or AMD VT (Virtualization Technology)
    • Intel/AMD VT (Virtualization Technology) Should be enabled from BIOS setup

    Required: If you haven’t already then you should enable Virtualization Technology (aka Intel VT or AMD-V).

    Furthermore, it’s highly recommended that you install macOS Sierra on SSD (Solid State Drive) instead of HDD (Hard Disk Drive) because you will have a much faster performance with SSD rather than HDD

    Step 4: Create a New Virtual Machine for macOS Sierra

    After installing VirtualBox, now you will need to create a new virtual machine on Virtualbox. Creating a virtual machine for macOS Sierra is kind of the same as you create a VM for the Windows Operating system or Linux but with some minor changes. In this post, I’ll outline those changes. Follow the steps below to create a new virtual machine for macOS Sierra using the VMDK file.

      1. Open up your VirtualBox application and click New.

        Create a New VM

      2. Click Expert Mode and select the following options then click Create.
        1. Type a suitable Virtual Machine Name.

      3. It’s time to edit the virtual machine to make it works. Select macOS Sierra VM and click on Settings. Now, bring the following changes to macOS Sierra VM.
        1. Under System>Motherboard, increase the Base Memory to 10248MB. However, you can use a bit lower memory if your system doesn’t have this much RAM.
        2. Uncheck Floppy from the Boot Order section.
        3. Under the Processor tab, increase the processors to 4 or higher.
          macOS Sierra Boot Order
          macOS Sierra Boot Order
          macOS Sierra Processor
          macOS Sierra Processor

      4. On the Display window, increase the Video Memory to 128MB.
        Increase macOS Sierra Video Memory

        Increase macOS Sierra Video Memory

    Step 5: Execute the VirtualBox Code

    Once you’ve created and customized your virtual machine, it’s time to run some codes in order to install macOS Sierra on VirtualBox. First, you should note your virtual machine name because later on, we will use it. Open the VirtualBox code which you should have downloaded from the “Download the Prerequisites” section of this post. If you’ve not downloaded, doesn’t matter. Just use the following code.
    Note: Before, you execute the code by command prompt. You should read the following steps.

    1. When you opened VirtualBox code via notepad or any other text editor, use the replace function of the program to Replace the “VM Name” with your virtual machine name. See the picture below to get an idea of how to do it.
      Replace VM name with macOS Sierra

      Replace VM name with macOS Sierra

    2. Now, you’ve two choices. First, if you want to fix your macOS Sierra screen resolution in the first place. You should also execute the following code. You have to change “VM Name” with your virtual machine name and HxV with a screen resolution such as “1280×720“. For more supported screen resolution on VirtualBox and detailed guide, visit fix macOS Catalina screen resolution on VirtualBox.

      Important Note: We highly recommend to quit the VirtualBox program before executing the code. If you don’t do it, your virtual machine might not proceed to the installation step.

      Exit VirtualBox

      Exit VirtualBox

    3. Once you replaced the “VM Name” with your virtual machine name, then run the code one by one via command prompt (CMD). You can open the command prompt by pressing the Windows+X key in Windows 10 and select Command Prompt from the list. Or simply press Windows key and type CMD. Click Run As Administrator and click Yes
      Execute macOS Sierra VirtualBox Code

      Execute macOS Sierra VirtualBox Code

      .

    4. Now, that you’ve executed the macOS Sierra VirtualBox code. Open the VirtualBox app then click the Start button to power on the VM. A black screen with a lot of white text will appear on the screen. Just wait for a few minutes and the macOS Sierra installation will start.

    How to Install Ubuntu Server on VirtualBox

    In this post I’ll show you how to install Ubuntu 18.04.3 LTS (Bionic Beaver) on Oracle’s VirtualBox. I’ll also demonstrate how to connect to the Ubuntu instance via SSH. This will form the basis for a second tutorial that will walk through installing and configuring Ruby on Rails on an Ubuntu server.

    Let’s get started!

    What Is VirtualBox?

    VirtualBox is a software virtualization package that you can install on your operating system (just as you would a normal program). It supports the creation and management of virtual machines into which you can install a second operating system.

    In VirtualBox terminology, the operating system on which you install VirtualBox (i.e. your regular OS) is called the host. The operating system you install within VirtualBox (i.e. inside the virtual machine) is called the guest.

    For this tutorial, I’ll be using Linux Mint 19.2 as the host OS, but there’s no reason you couldn’t use a different Linux distro, or macOS, or Windows (if you’re so inclined).

    Install VirtualBox

    The first thing to do is to get VirtualBox installed. I’ll not go into much detail here, as there are comprehensive instructions for all of the main operating systems on the project’s homepage.

    Personally, I downloaded and installed the deb package for Ubuntu 18.04 / 18.10 / 19.04. This is because the VirtualBox version in the Mint repos is slightly outdated and I wanted to be running the latest version.

    Download Ubuntu Server

    The next thing to do is to grab a copy of Ubuntu Server. You can do this from their download page. This will download a 889MB iso file to your PC.

    At the time of writing the current LTS version is Ubuntu Server 18.04.3 and this is what I’ll be using. It’s supported until April 2023 and is available as 64-bit only.

    Create a New Virtual Machine

    Start up VirtualBox. This should open the VirtualBox Manager, the interface from which you will administer all of your virtual machines.

    Welcome to VirtualBox

    Next Click on New (in the top right of the VirtualBox Manager), give your virtual machine a name and the two drop down menus should automatically update.

    Name and operating system

    Click Next. The wizard will now ask you to select the amount of memory (RAM) in megabytes to be allocated to the virtual machine. I chose 2GB (2048 megabytes).

    Memory size

    Click Next and you will be prompted to add a virtual hard disk to the new machine. Make sure that Create a virtual hard disk now is selected, then press Create.

    Hard disk

    Now we need to choose the file type for the new virtual hard disk. Make sure that VDI (VirtualBox Disk Image) is checked and press Next.

    Hard disk file type

    On the next screen you will be asked whether the new virtual hard disk should grow as it is used (dynamically allocated) or if it should be created at its maximum size. Make sure that dynamically allocated is selected, then click Next.

    Storage on physical hard disk

    Finally, select the size of the virtual hard disk in megabytes. The default size of 10GB should be plenty, but feel free to increase this as you see fit. Then click Create.

    File location and size

    The hard disk should now be created and after a short while you should find yourself back in the VirtualBox Manager. You should be able to see your newly created virtual machine listed on the left.

    Install Ubuntu Server in the Virtual Machine

    Make sure your virtual machine is selected and press Start. VirtualBox Manager will ask you to select a virtual optical disk file or a physical optical drive to start the virtual machine from. Select the iso file you downloaded previously and press Start.

    Select start-up disk

    The Ubuntu installation process will now begin. It consists of thirteen steps and is quite painless.

    The Welcome Screen

    Here you should select your preferred language. I’m using English.

    The Welcome Screen

    The Keyboard Configuration Screen

    Here you should select a keyboard layout. As I’m using a German keyboard, I asked Ubuntu to detect my layout, which it did with a couple of simple questions.

    The Keyboard Configuration Screen

    The Network Connections Screen

    Here Ubuntu will attempt to configure the standard network interface. Normally you can just accept the default and select Done.

    The Network Connections Screen

    The Configure Proxy Screen

    If your system requires a proxy to connect to the internet (mine doesn’t), enter its details in the next dialogue. Then select Done.

    The Configure Proxy Screen

    The Ubuntu Archive Mirror Screen

    If you wish to use an alternative mirror for Ubuntu, you can enter the details here. Otherwise accept the default mirror by selecting Done.

    The Ubuntu Archive Mirror Screen

    The Filesystem Setup Screen

    The installer can guide you through partitioning an entire disk or, if you prefer, you can do it manually. If you choose to partition an entire disk you will still have a chance to review and modify the results before Ubuntu is installed. I selected Use An Entire Disk.

    I was then prompted to select my virtual machine’s hard disk as the disk to install to, before being shown a summary of what the installer would do. As this is a “destructive action”. I was asked to confirm my choice with Continue.

    The Filesystem Setup Screen

    The Profile Setup Screen

    Here you are required to enter:

    • Your (real) name
    • Your server’s name
    • Your username
    • Password

    Fill these details out as you see fit.

    The Profile Setup Screen

    The SSH Setup Screen

    Here we have a chance to install the OpenSSH server package. We’ll need this to connect to the virtual machine via SSH later on, so ensure that you select it.

    You also have the opportunity to import your SSH keys from GitHub or Launchpad. I selected No for this option.

    The SSH Setup Screen

    The Featured Server Snaps screen

    Here you can select from a list of popular snaps to install on your system. Snaps are self-contained software packages that work across a range of Linux distributions. I didn’t select any.

    The Featured Server Snaps screen

    And that’s it, the installation is complete. Ubuntu will ask you to remove the installation medium (which you can do via Devices > Optical Drives > Remove disk from virtual drive > Force unmount) and then reboot.

    If this option is grayed out, you’re good to go. Just reboot.

    Up and Running with SSH

    Once your virtual machine has rebooted and you have logged in, you’ll probably notice that some packages can be updated.

    Let’s fix that:

    Now let’s double check that SSH is installed (it should be if you selected the option Install OpenSSH server during instalation).

    If you get a “command not found” error, you can install it with:

    The next step is to give our Ubuntu server an IP address on our local network. To do this, power off the virtual machine using or Machine > ACPI Shutdown.

    Then, in VirtualBox Manager, click on the Network panel on the right. Change the setting Adapter 1 > Attached to to “Bridged Adapter” and click OK.

    VirtualBox Manager - Network Adapter 1

    Start up your virtual machine, then enter (in the guest) and note the IP address assigned to your main network adapter. In my case this was .

    Note: it is also possible to stick with the original NAT interface and SSH into the guest using port forwarding. You can read more about that here. You can find information on all of the VBox network settings in this comprehensive guide.

    Starting and Stopping VirtualBox in Headless Mode

    You might have noticed, working with the VirtualBox Manager and the guest OS is a bit of a pain. If you’re going to continue doing this, you should at least install the guest additions, as well as enable clipboard support.

    There is a slightly nicer way however — you can start and stop the virtual machine using the VBoxManage command from your terminal.

    To power on:

    And to power off:

    Where “Ubuntu Server 18.04.3” is whatever you called your virtual machine (the name it has in the VirtualBox Manager GUI).

    Connecting to the Ubuntu Server

    Let’s go ahead and start the Ubuntu server in headless mode, before connecting to it via SSH.

    Note: The following commands should be run on your host.

    On most *nix systems, the SSH client software should be part of the default installation. If you don’t have it available, you should be able to grab it from the repos, like so:

    or just hit DuckDuckGo.

    Then (ensuring that you replace “jim” and the IP address with your corresponding values) you can connect like so:

    This will give you a warning that the host’s authenticity cannot be established and ask you if you want to continue connecting. Answer “yes”.

    Next, it will prompt you for your password. Enter it and you will be connected to your Ubuntu server from your host OS.

    Connected to the Ubuntu server via SSH

    For Windows Users

    If you’re running Windows you’ll need to install a SSH client such as PuTTY.

    When PuTTY starts, a window titled PuTTY Configuration should open. This window has a configuration pane on the left, a Host Name field and other options in the middle, and a pane for saving session profiles in the lower right area.

    For simple use, all you need to do is to enter the IP address of the host you want to connect to in the Host Name field and click Open.

    PuTTY Configuration

    Generate and Install a SSH Key Pair

    SSH keys offer a secure manner of logging into a server without the need of a password.

    In a nutshell, this depends upon you generating a public and a private SSH key pair. The private key is kept on your PC (and should be guarded carefully). The public key is copied over to the server you wish to connect to.

    SSH keys are a complex subject and as such, out of the scope of this tutorial. If you’d like to find out more, I recommend looking for a dedicated tutorial (such as this one).

    Generate the Keys

    On *nix systems (Windows users see the next section), you can generate your key pair with the following command:

    The option instructs ssh-keygen to store the private key in the new OpenSSH format instead of the old (and more compatible PEM format). This is advisable, as the new OpenSSH format has an increased resistance to brute-force password cracking.

    The option is used to set the key length to 4096 bits instead of the default 1024 bits for security reasons.

    In the following dialogue you will be required to answer a couple of questions:

    • Where to save the newly generated key pair
    • Which passphrase to use

    Here you can accept the default location and leave the passphrase blank by pressing .

    ssh-keygen will then output a summary of what it has done:

    Copy the Public Key to the Ubuntu Server

    To copy the public key to the Ubuntu server use:

    Where is the path to your public key, taken from the output above. And where should be altered to reflect your details.

    The command will run and you should be asked for your server password. Enter it, then attempt to log into the server like so:

    This time you should be in without a password.

    For Windows Users

    You should be able to use a tool like PuTTYgen to achieve the same thing. Here is a tutorial on using PuTTYgen to create a new key pair for authentication.

    You will have a little more leg work when it comes to copying the key to the server, where you will need to add the public key to a file.

    You can do that like so:

    This will create the appropriate file, then open the nano editor into which you can copy your newly generated public key.

    When you’re done, press + to save your changes and exit nano.

    Conclusion

    This has been quite a long post, but by the end of it you should have a working installation of Ubuntu Server running on VirtualBox that you can connect to from your host operating system via SSH.

    As mentioned, this will form the basis for a future tutorial on deploying a Ruby on Rails app to an Ubuntu server.

    If you have any questions or feedback, I’d be glad to hear your from you in the comments.

    Thereafter, head out to the RHEL 8 download page and download the RHEL 8 ISO file for free. Once you have downloaded the ISO image, you can choose to create a bootable USB drive using Rufus or any other utility of your choice.

    If you wish to install RHEL 8 on VirtualBox as I’ll demonstrate, an ISO image alone is enough.

    Installing RHEL 8 on VirtualBox

    1. Open your VirtualBox and click on the “New” icon. Assign a preferred name to your virtual machine and click “Next”.

    Create New Virtual Machine

    2. In the next step, allocate some memory for your virtual machine. In this case, I have chosen to assign a memory capacity of 2048 MB.

    Set Memory for RHEL 8

    3. In the next window, select “Create a virtual hard disk now” and click “Create”.

    Create Hard Disk for RHEL 8

    4. Ensure that the Hard disk file type is set to VDI (VirtualBox Disk Image) and click “Next”.

    Create VirtualBox Disk Image

    5. Next, select the ‘Dynamically allocated” option and click “Next”.

    Set Storage for RHEL 8

    6. Then allocate some hard disk space for your virtual machine. In this example, I have chosen to assign 25.33 GB to my VM. Once done, click on the “Create” button.

    Set Hard Disk Space for RHEL 8

    7. The only thing remaining is to point the VM to the RHEL 8 ISO image. SO click on “Storage” –> “Controller: IDE” and click on the ‘empty’ disk and select your ISO image file.

    Add RHEL 8 ISO Image

    8. When all’s done. Click on the “Ok” button and click on the “Start” button.

    Start RHEL 8 VM

    9. On the first screen after powering on the VM, the following options will be printed on the screen. Select the first option “Install Red Hat Enterprise Linux 8.1.0”.

    Select Install RHEL 8 from Grub Menu

    10. Thereafter you will observe some boot messages on the screen as RHEL 8 boots up.

    RHEL 8 Booting

    11. Once the RHEL 8 is done with the booting process, the window below will prompt you to select the installation language. Select your preferred language and hit the “Continue” button.

    Select RHEL 8 Installation Language

    12. A summary of all the critical components that need to be configured will be displayed as shown. Ensure you click on every one of them and tweak the settings according to your preferences.

    14. Next, click on the “Language Support” option and select your preferred language and click “Done”.

    15. Be sure to adjust your ‘Time and date’ settings appropriately.

    Select Time and Date

    16. In the ‘Software selection’ option choose your preferred Base environment and click ‘Done’. In this case, I have chosen to go with the Workstation option which is quite okay for a desktop PC.

    Select Workstation Installation

    17. In the ‘Network and hostname’ section, turn on the toggle next to the network interface.

    Enable Network in RHEL 8

    18. In the “Installation Destination’ select the hard drive that you’d want to install RHEL on and feel free to select either ‘Automatic’ or ‘Manual’ partitioning.

    In this case, I will select the ‘Automatic’ partitioning option for the system to automatically partition the hard disk and save the changes. For a production server, however, you may be required to manually partition the hard drive to suit your preferences.

    Select Automatic RHEL 8 Partitioning

    19. And lastly, in the ‘System Purpose’ setting, ensure that you select the ‘Development/Test’ option as the usage for your system and leave all the other entries unchanged. Then click ‘Done’.

    Set RHEL 8 System Purpose

    20. With all the salient parameters, click on the “Begin Installation” button for the installation to commence. But while at it, you will be required to provide a root password and create a new user.

    Set Root Password for RHEL 8

    22. Next, create a new user by specifying a username followed by the user’s password.

    Create New RHEL 8 User

    23. Once everything is set, the installer will begin to install RHEL 8. The installation process ensures that all the system packages and the grub bootloader are installed. Once the installation is complete, click on the ‘Reboot’ button to restart the system.

    RHEL 8 Installation Complete

    24. At this point, it is safe to remove your installation media, or in this case, unmount the ISO image file. During the reboot process, select the first grub entry and hit ENTER.

    Select RHEL 8 from Grub

    25. Upon rebooting, two things will be required of you, Firstly, you will be required to accept the License Agreement and later register your RHEL 8 system with Red Hat.

    Accept RHEL 8 License Agreement

    26. At this point, accepting the license agreement is what is crucial. The latter can be done later once we are done with the installation of the system. Therefore, click on “License Information” and check off the “I accept the License Agreement” checkbox and click “Done”.

    View and Accept License Agreement

    27. Finally, click on the “Finish configuration” tab. The GNOME login screen will be displayed.

    RHEL 8 Gnome Login

    28. Log in with your username and password. This will usher you to the GNOME desktop environment as shown.

    Registering RHEL 8 for RedHat Subscription Management

    29. When you try updating your system packages on the terminal, you will encounter the error below. This implies that your system has not yet been registered.

    $ sudo dnf update
    RHEL 8 RedHat Subscription Management Error

    30. A Red Hat subscription allows you to get the latest package & security updates and bug fixes as well.

    To register your RHEL 8 system, run the command:

    $ subscription-manager register --username your-redhat-developer-username --password your-redhat-password

    31. Thereafter, execute the command below to enroll your RHEL system to a subscription.

    $ subscription-manager attach --auto

    32. If everything went according to plan, you should receive the notification as shown.

    Installed Product Current Status: Product Name: Red Hat Enterprise Linux for x86_64 Status: Subscribed

    33. Once you’ve been subscribed, you can now proceed to update your system and install system packages.

    $ sudo dnf update
    Update RHEL 8 System

    Renewing the RHEL 8 Subscription

    The trial period for RHEL 8 developer subscription lapses after 1 year. The good news is that you can readily renew your RHEL subscription for free after every year to continue enjoying your OS.
