Are you looking to enable virtualization in your Ubuntu virtual machine? If so, you’ve come to the right place!
In this blog post, we’ll show you how to do just that. Virtualization can be a great way to improve your workflow, and it’s also perfect for testing and development purposes. So without further ado, let’s get started!

ENABLE VIRTUALIZATION IN UBUNTU:
1) If you want to enable virtualization on your system, you’ll need to go into the BIOS and enable it. This is usually done by hitting a key during bootup (often F12, F10, or ESC) to bring up a menu that allows you to change the boot order or enter the BIOS setup.
Once you’re in the BIOS, look for an option that says something like “Virtualization,” “VT-x,” “SVM,” or “AMD-V.” Enable it and then save and exit the BIOS.
2) If you’re running Ubuntu in a virtual machine, you’ll need to enable hardware virtualization for the VM in order for nested virtualization to work.
In VMware Player, this can be done by going to VM > Settings > Hardware > Processors and checking the box next to “Virtualize Intel VT-x/EPT or AMD-V/RVI.”
In VirtualBox, go to VM > Settings > System > Processor and check the box next to “Enable VT-x/AMD-V.”
3) Once hardware virtualization is enabled in your system’s BIOS and/or VM settings, you can verify that it’s working by running the following command:
egrep -c ‘(vmx|svm)’ /proc/cpuinfo
If hardware virtualization is enabled, this command should return a non-zero number; if it returns 0, then hardware virtualization is not enabled on your system.
What is Virtualization?
Virtualization allows you to run an entire operating system on top of another operating system.
In other words, you can have an entire Windows computer inside your Ubuntu computer.
That Windows computer can run any Windows software, and it will run it just as if it were running on a real, physical Windows machine.
Virtualization is useful for a number of reasons. It allows you to test new software on a safe, isolated environment before you install it on your main operating system.
It also allows you to run multiple operating systems at the same time on the same computer, so you can easily switch between them as needed.
One of the most popular virtualization software programs is VirtualBox, which is developed by Oracle.
VirtualBox is free to use and is available for all major operating systems, including Linux, Windows, and Mac OS X.
Why use Virtualization?
There are many reasons why you might want to use virtualization with Ubuntu. Perhaps you need to test an app or website in multiple browsers, or on different versions of Ubuntu.
Maybe you want to run a server in a virtual machine (VM) so that it’s isolated from your main computer.
Or perhaps you need to run Windows so that you can use certain apps that are only available for that operating system.
Whatever your reason, virtualization can be a great way to improve your workflow and get more out of your computer.
How to enable virtualization in Ubuntu?
There are a few different ways to enable virtualization in Ubuntu, but we will focus on two of the most popular methods: using the BIOS or UEFI settings, and using the Linux kernel parameters.
Enabling virtualization in the BIOS or UEFI settings is typically the easiest method, but it may not be available on all systems.
To check if your system supports this method, you can simply look for a setting called “Virtualization” or “VT-x” in the BIOS or UEFI settings menu. If you see this setting, simply enable it and then reboot your system.
If your system does not have a setting for virtualization, or if you are unsure whether it is enabled, you can also try using Linux kernel parameters.
To do this, you will need to edit your system’s GRUB configuration file. For most systems, this file is located at /etc/default/grub.
In this file, look for the line that starts with “GRUB_CMDLINE_LINUX” and add the following parameter to it: “intel_iommu=on”.
After saving your changes to this file, update your GRUB configuration with the command “sudo update-grub” and reboot your system.
What are the benefits of virtualization?
Virtualization provides a number of benefits, chief among them being more efficient use of hardware resources and increased flexibility in server deployments.
Because each virtual machine running on a physical server can function as an independent server, organizations can make better use of their hardware resources.
For example, rather than having one physical server dedicated to running a particular application, that same physical server could run multiple virtual machines, each hosting a different application.
This results in increased utilization of hardware resources and reduced costs.
In addition, virtualization increases flexibility by allowing organizations to quickly and easily deploy new servers or change the configuration of existing servers.
For example, if an organization needs to deploy a new application quickly, it can simply create a new virtual machine and install the application on that virtual machine.
This is much simpler and faster than provisioning a new physical server and installing the application on that server.
How to use virtualization in business?
Its use in business settings has exploded in recent years, as more and more organizations have come to rely on virtual machines (VMs) to increase efficiency, improve agility, and lower costs.
Virtualization can be used for a variety of purposes in business, from running multiple operating systems on a single server to creating test and development environments that mirror production systems.
In this article, we’ll explore some of the most common uses of virtualization in business, along with some tips on how to get started.
One of the most common uses of virtualization in business is running multiple operating systems on a single server. This can be done for a number of reasons, including consolidating servers, reducing hardware costs, and increasing flexibility.
If you’re thinking about using virtualization to run multiple operating systems on a single server, there are a few things you’ll need to keep in mind.
First, you’ll need to choose a virtualization platform. There are many different options available, so take some time to research your options and choose the one that’s right for your needs.
Second, you’ll need to ensure that your server has enough resources (memory, CPU, storage) to support the number of VMs you plan to run.
And finally, you’ll need to make sure that your operating system licenses allow for virtualization.
Another common use of virtualization in business is creating test and development environments that mirror production systems.
This can be an invaluable tool for organizations that need to test new software or configurations before deploying them in production.
It can also help developers create consistent environments for testing their code.
If you’re interested in using virtualization to create test and development environments, there are a few things you’ll need to keep in mind.
First, you’ll need to ensure that your test and development environment exactly mirrors your production environment.
This means having identical hardware configurations and identical software setups.
Second, you’ll need to make sure that your team has the skills and knowledge necessary to work in a virtualized environment.
And finally, you’ll need to have a plan for migrating changes from your test and development environment into production.
How to use virtualization in education?
Virtualization technology can be used in education to create a “virtual” computer lab, where students can access a wide variety of software applications and operating systems on a single, physical machine.
This can be especially beneficial for schools with limited resources, as it can provide students with access to a wider range of educational materials.
Conclusion
If you want to use virtualization on your Ubuntu VM, you’ll need to enable it in the BIOS settings.
To do this, reboot your VM and press the key that allows you to enter the BIOS settings (usually F2 or F12).
Once in the BIOS settings, find the section that relates to virtualization and ensure that it is enabled.
After saving your changes and exiting the BIOS, you should be able to use virtualization on your Ubuntu VM without any issues.
