Install KVM on Ubuntu 20.04: Best Virtualization Solution
In this guide, we want to teach you How To Install KVM on Ubuntu 20.04. A kernel-based virtual machine (KVM) is a virtualization infrastructure built for Linux OS and designed to operate on x86-based processor architecture. KVM is developed by Red Hat Corporation to provide a virtualization solution and services on the Linux operating system platform. It is designed over the primary Linux OS kernel.
KVM is a type of hypervisor that enables, emulates, and provides for the creation of virtual machines on operating systems. These machines are built on top of the Linux kernel, using operating systems such as Linux, Ubuntu, and Fedora. It can be installed on all x86 processors and provides separate instruction set extensions for Intel and AMD processors.
Now follow the guide steps below on the Orcacore website to complete the KVM Virtualization setup on Ubuntu 20.04.

Steps To Install KVM on Ubuntu 20.04
To complete the KVM Virtualization setup, you must log in to your server as a non-root user with sudo privileges. To do this, you can follow our guide the Initial Server Setup with Ubuntu 20.04.
1. Check Virtualization Support on Ubuntu 20.04
Before installing KVM, you need to make sure that KVM is compatible with your system. Otherwise, you will keep running into errors, and KVM won’t install properly.
First, update and upgrade your local package index with the following command:
sudo apt update && sudo apt upgrade -yTo check whether the Ubuntu system supports virtualization, run the following command:
egrep -c '(vmx|svm)' /proc/cpuinfoIf the output you get is greater than 0, that means KVM is compatible with the system and can be installed.
To check if your system supports KVM virtualization execute the command:
sudo kvm-ok
If the “kvm-ok” utility is not present on your server, install it by running the apt command:
sudo apt install cpu-checker
Now execute the “kvm-ok” command to probe your system.
sudo kvm-ok
2. Installing KVM on Ubuntu 20.04
At this point, you need to install the required packages and dependencies by running the command below:
sudo apt install -y qemu qemu-kvm libvirt-daemon libvirt-clients bridge-utils virt-manager
Then, you need to check that the virtualization daemon – libvritd-daemon – is running on Ubuntu 20.04:
sudo systemctl status libvirtd
Also, you can use the command below to enable it to start on boot:
sudo systemctl enable --now libvirtd
To check if the KVM modules are loaded, run the command:
lsmod | grep -i kvm
Now add your user to KVM and libvirt group to get up KVM and avoid running into issues. The user can be added to the KVM group using this command:
sudo usermod -aG kvm $USERNext, add the user to the libvirt group by using this command:
sudo usermod -aG libvirt $USERConclusion
At this point, you learn to test the compatibility between KVM Virtualization and your Ubuntu system. After that, you installed the necessary KVM packages and then installed KVM.
