-====== KVM ======
-===== Installation =====
-Install all the required for the installation of Qemu, KVM hypervisor, and Libvirt
-  # apt install qemu-system libvirt-daemon-system qemu-utils virt-manager
-  * qemu-system: is an open source virtualizer that provides hardware emulation for the KVM hypervisor. It acts as a virtual machine monitor together with the KVM kernel modules, and emulates the hardware for a full system such as a PC and its associated peripherals.
-  * virt-manager: Virt-Manager is a graphical user interface (GUI) tool for managing virtual machines through libvirt-daemon.
-  * libvirt-daemon-system: provides API libraries that enables GUI apps such as virt-manager to communicate with libvirtd daemon, a system service libvirtd , and a virsh CLI tool
-  * qemu-utils: Various utilities e.g. for manipulating disk images
-  * virtinst: Allows to create Virtual Machines (VMs) from the command-line.
-Verify that the virtualization daemon, libvritd-daemon, is operating before moving on. Execute the command to achieve this.

-Check if libvirtd service will start automatically at boot time.
-<code>
-# systemctl is-enabled libvirtd
-Output:
-enabled
-</code>
-If disabled run the following command to have it boot automatically:
-  # systemctl enable --now libvirtd
-Use the following command to determine whether the KVM modules are loaded:
-<code>
-$ lsmod | grep -i kvm
-kvm_intel             380928  0
-kvm                  1142784  1 kvm_intel
-irqbypass              16384  1 kvm
-</code>
-===== Configuration =====
-In order to manage virtual machines as a regular user, that user needs to be added to the libvirt group:
-  # adduser <youruser> libvirt
