How to install KVM on CentOS 8 Headless Server

To install KVM on a CentOS 8 headless server, you can use the following steps:

1. Install the KVM and libvirt packages:
   sudo yum install qemu-kvm libvirt
   This installs the required packages for KVM and libvirt, which is a virtualization API used by KVM.

2. Enable the libvirt daemon:
   sudo systemctl enable libvirtd
sudo systemctl start libvirtd
   These commands enable and start the libvirt daemon, which is responsible for managing virtual machines on the system.

3. Add your user to the libvirt group:
   sudo usermod -a -G libvirt $USER
newgrp libvirt
   These commands add your user to the libvirt group and refresh the group membership.

You can verify the installation by running the virsh --version command, which should display the version of libvirt that you have installed.

KVM (Kernel-based Virtual Machine) is a virtualization solution for Linux that allows you to run multiple virtual machines on a single physical host. It is widely used in enterprise environments for server consolidation, testing, and development.

Note: These steps assume that you are using CentOS 8 and the yum package manager. If you are using a different Linux distribution or a different package manager, you may need to use different commands to install KVM.
