However, this is a very complex task and we do not recommend this procedure to inexperienced users: correct configuration of a virtual machine may sometimes be very difficult. <\/p>\n<p>This guide will describe the configuration of the KVM hypervisor (Kernel-based Virtual Machine). We will take the example of the server running on Ubuntu 22.04 LTS. However, the instructions provided below may be helpful if any Linux distribution is used since KVM is a part of the kernel.<\/p>\n<p>Below we will show how to use KVM with the help of the terminal and on Linux with a graphical shell.<br \/>\n<!--more--><\/p>\n<div id=\"ez-toc-container\" class=\"counter-hierarchy ez-toc-transparent\">\n<div class=\"ez-toc-title-container\">\n<p
