KVM (Kernel-based Virtual Machine) is a virtualization solution for Linux that turns the kernel into a hypervisor. QEMU is a generic and open-source machine emulator and virtualizer. In this guide, we will walk you through the steps to install KVM/QEMU on Manjaro or Arch Linux.

Step 1: Update Your System

Before you begin, ensure your system is up to date. Open your terminal and run the following commands:

sudo pacman -Syu

Step 2: Install KVM/QEMU

Install the necessary packages for KVM and QEMU:

sudo pacman -S qemu virt-manager virt-viewer dnsmasq

Step 3: Load KVM Module

Check if your CPU supports virtualization. Run:

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

If the output is greater than 0, you can load the KVM module:

sudo modprobe kvm

For Intel CPUs, use:

sudo modprobe kvm-intel

For AMD CPUs, use:

sudo modprobe kvm-amd

Step 4: Add Your User to the Libvirt Group

To manage virtual machines, add your user to the libvirt group:

sudo usermod -aG libvirt $(whoami)

Log out and log back in to apply the changes.

Step 5: Start and Enable the Libvirt Daemon

Start the libvirt service and enable it to run on startup:

sudo systemctl start libvirtd

sudo systemctl enable libvirtd

Step 6: Verify the Installation

You can verify the installation by running:

virsh list --all

If you see an empty list without errors, KVM/QEMU is successfully installed.
