KVM (Kernel-based Virtual Machine) is an open source full virtualization solution for Linux systems, including Ubuntu… Like VirtualBox, VMware Workstation, KVM is a virtualization infrastructure for the Linux kernel that turns it into a hypervisor….

This brief tutorial shows students and new users how to install KVM kernel modules on Ubuntu server to enable full virtualization….

If you can’t install VirtualBox or VMware Workstation virtualization solutions on Ubuntu, then you can try KVM…. After installing, use KVM module to install and run multiple virtual machines (guest) on Linux servers…

These virtual machine can be managed via virt-manager graphical user interface or virt-install & virsh cli commands….When you’re ready to install KVM, follow the steps below:

Step 1: Check your System

Not all systems can install and run KVM modules…… If your’re running a server that isn’t compatible, KVM can’t be used on it… to check, run the commands below to install a CPU checker tool:

sudo apt install cpu-checker
sudo kvm-ok

After installing, the above commands check the CPU compatibility with KVM… If KVM is compatible you should get message that KVM acceleration can be used…

KVM acceleration can be used

if KVM isn’t compatible for your system, you’ll get a message that reads

INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used

The message above shows you can’t run KVM…
