How to Install KVM on Ubuntu 22.04

KVM is a virtualization technology that is open-source and permits several virtual machines to operate on a single Linux host machine like Ubuntu 22.04. It is a popular choice for creating and managing virtualized environments due to its performance, security, and cost-effectiveness. It also offers an abstraction layer between VMs and hardware. More specifically, KVM can virtualize ARM, x86, and other architectures.

In this blog, we will check out the method for the installation and uninstallation of KVM on Ubuntu 22.04.

sudo apt update

Step 2: Upgrade the package

Run the mentioned command in the terminal for upgrading the packages:

sudo apt upgrade

Note: Run the following command in the terminal to check if KVM is compatible. If the command returns a non-zero value, it means that the CPU supports virtualization.

egrep -c '(vmx|svm)' /proc/cpuinfo

Step 3: Install KVM

Install KVM by executing the command below in the terminal:

sudo apt-get install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils -y

To enable, start, and check the status of libvirtd services, execute the mentioned commands:

sudo systemctl enable libvirtd
sudo systemctl start libvirtd
sudo systemctl status libvirtd

Step 5: Add user to KVM

For adding your user to KVM, type the mentioned command in the terminal:

sudo usermod -aG kvm author

Note:author” is the username.

Step 6: Add user to libvirt group

Likewise, add the user to the libvirt group:

sudo usermod -aG libvirt author

Step 7: Create a Bridge Network for VMs

Next, type out the following command for establishing a bridge network:

sudo nano /etc/netplan/01-netcfg.yaml

After that, append the mentioned configuration in the opened file:




dhcp4: false

dhcp6: false



interfaces: [eth0]

dhcp4: false

addresses: []

macaddress: 01:26:3b:4b:1d:43


- to: default


metric: 100


addresses: []


stp: false

dhcp6: false

version: 2

Hit “CTRL+O” and “CTRL+X” to save and exit the file.

Step 8: Use Netplan to apply changes

Execute the mentioned command for applying the configuration:

sudo netplan apply
