Steps to install KVM

---

1. Check if virtualization is enabled.

cat /proc/cpuinfo | grep -Ec '(vmx|svm)'

In this command, we are printing the contents of /proc/cpuinfo, then using grep for pattern matching. vmx is the name for Intel's virtualization and svm is AMD's. If the output is 0, virtualization is disabled in BIOS, otherwise it's on.

2. Install required packages

sudo apt install -y qemu-kvm virt-manager libvirt-daemon-system virtinst libvirt-clients

• qemu-kvm – An opensource emulator and virtualization package that provides hardware emulation.
• virt-manager – A Qt-based graphical interface for managing virtual machines via the libvirt daemon.
• libvirt-daemon-system – A package that provides configuration files required to run the libvirt daemon.
• virtinst – A set of command-line utilities for provisioning and modifying virtual machines.
• libvirt-clients – A set of client-side libraries and APIs for managing and controlling virtual machines & hypervisors from the command line.

3. Start and enable virtualization daemon

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

Tip

After viewing status of the libvirtd service, press q to exit out of the view.

4. Add user to KVM and libvirt group

sudo usermod -aG kvm $USER
sudo usermod -aG libvirt $USER

5. Launch KVM Virtual Machine Manager from App Launcher.

6. QEMU/KVM should show connecting followed by connected in the app. Now, you can launch as many virtual machines as you want!
