Install KVM on CentOS 8

In this tutorial, we will show you how to install KVM on CentOS 8. For those of you who didn’t know, KVM (Kernel-based Virtual Machine) is the virtualization solution for Linux. It consists of a loadable kernel module that allows the Linux Kernel to work as a Hypervisor. KVM provides hardware-assisted virtualization for a wide variety of guest operating systems.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of KVM on a CentOS 8 server.

Step 1. First, let’s start by ensuring your system is up-to-date.

[[email protected] ~]# lscpu | grep Virtualization

In CentOS 8, virtualization components including KVM and QEMU hypervisors are bundled in virt the module. Therefore, it is really simple now to configure a KVM virtualization host in CentOS 8:

sudo dnf install virt-top libguestfs-tools
