+= KVM Installation =
+
+KVM, (kernel-based Virtual Machine) is a free and opensource virtualization platform for the Linux kernel. When installed on a Linux system, it becomes a Type-2 hypervisor.
+
+Here we look at how to install KVM on Ubuntu 20.04 LTS.
+
+First update the Ubuntu package repository.
+
+Before installing KVM on Ubuntu, we are first going to verify if the hardware supports KVM. A minimum requirement for installing KVM is the availability of CPU virtualization extensions such as AMD-V and Intel-VT.
+
+To check whether the Ubuntu system supports virtualization, run the following command.
+
+{{{
+egrep -c '(vmx|svm)' /proc/cpuinfo
+}}}
+
+An outcome greater than 0 implies that virtualization is supported
+
+To check if your system supports KVM virtualization execute the command
+{{{
+sudo apt install cpu-checker
+sudo kvm-ok
+}}}
+
+With the confirmation that our system can support KVM virtualization, we are going to install KVM, To install KVM, virt-manager, bridge-utils and other dependencies, run the command
+
+{{{
+apt install -y qemu qemu-kvm libvirt-daemon libvirt-clients virt-manager bridge-utils
+}}}
+
+Before proceeding further, we need to confirm that the virtualization daemon – libvritd-daemon – is running. To do so, execute the command
+
+{{{
+sudo systemctl status libvirtd
+systemctl enable --now libvirtd
+}}}
+
+Check if KVM modules are loaded,
+{{{
+lsmod | grep -i kvm
+}}}

+
+To view available Guest os variants,
+
+{{{
+apt install libosinfo-bin
+osinfo-query os
+}}}
