In this video tutorial, we will cover how to install KVM (Kernel-based Virtual Machine) on Ubuntu 24.04 LTS system and demonstrate creating a virtual machine using the virt-manager application.
########## KVM Installation Steps on Ubuntu 24.04 ##############
1) Package Apt Repository Packages Index
sudo apt update
2) Check if Virtualization is enabled
egrep -c ‘(vmx|svm)’ /proc/cpuinfo
Install the cpu-checker package
sudo apt install -y cpu-checker
Another way to check if KVM virtualization is enabled
kvm-ok
3) Install KVM on Ubuntu 24.04
sudo apt install -y qemu-kvm virt-manager libvirt-daemon-system virtinst libvirt-clients bridge-utils
4) Enable and start virtualization daemon
sudo systemctl enable –now libvirtd
sudo systemctl start libvirtd
Check virtualization daemon is running
sudo systemctl status libvirtd
5) Add Your Local User to the KVM and Libvirt Group
sudo usermod -aG kvm $USER
sudo usermod -aG libvirt $USER
6) Create Network Bridge using netplan
Create a file with following content
sudo vi /etc/netplan/01-netcfg.yaml
network:
version: 2
renderer: NetworkManager
ethernets:
ens33:
dhcp4: false
dhcp6: false
bridges:
br0:
interfaces: [ens33]
dhcp4: false
addresses: [192.168.2.120/24]
routes:
– to: default
via: 192.168.2.1
metric: 100
nameservers:
addresses: [8.8.8.8]
save and close the file.
sudo chmod 600 /etc/netplan/*.yaml
Now, run following command to apply above network changes
sudo netplan apply
7) Launch KVM Virt-Manager and Create Virtual Machines
