How to Install a KVM in Arch Linux

If you’re running Arch Linux and want to set up a KVM (Kernel-based Virtual Machine), you’re in the right place. KVM is a powerful, open-source virtualization solution built into the Linux kernel. With it, you can run multiple virtual machines (VMs) efficiently on a single host.

This guide walks you through installing KVM on Arch Linux — no fluff, just the steps that matter.

Step 1: Check for Virtualization Support

First, make sure your CPU supports virtualization:

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

• If the result is 0, your CPU doesn’t support virtualization or it’s disabled in BIOS/UEFI.
• If it’s 1 or higher, you’re good to go.

To double-check support from the kernel:

lsmod | grep kvm

You should see kvm_intel or kvm_amd listed.

Step 2: Install the Necessary Packages

Install the core virtualization packages:

sudo pacman -Syu
sudo pacman -S qemu virt-manager virt-viewer dnsmasq vde2 bridge-utils openbsd-netcat libvirt

These packages include:

• qemu: Emulator and virtualizer
• virt-manager: GUI to manage VMs
• libvirt: Toolkit to interact with virtualization capabilities

Step 3: Enable and Start the Libvirt Service

Enable and start libvirtd:

sudo systemctl enable libvirtd.service
sudo systemctl start libvirtd.service

Check its status to confirm:

sudo systemctl status libvirtd.service

Step 4: Add Your User to the libvirt Group

To manage VMs without root, add your user to the libvirt group:

sudo usermod -aG libvirt $(whoami)

Then reboot or log out and back in to apply the group changes.

Step 5: Configure libvirt Networking (Optional but Recommended)

By default, libvirt sets up a NAT-based virtual network. To confirm:

virsh net-list --all

You should see a default network. If it’s not active, enable it:

virsh net-start default
virsh net-autostart default

Step 6: Launch Virt-Manager and Create Your First VM

Now, fire up the Virtual Machine Manager:

virt-manager

From here:

1. Click “Create a new virtual machine”.
2. Choose an ISO or existing disk image.
3. Allocate CPU, memory, and disk space.
4. Finish setup and start your VM.

Bonus: Prefer the Command Line?

If you like working in the terminal, you can also set up KVMs using QEMU CLI. It gives you full control without relying on a GUI.

Wrapping Up

Installing KVM on Arch Linux isn’t complicated if you know the steps. With just a few commands, you’re ready to run powerful virtual machines right from your desktop. Whether you’re testing distros, developing apps, or just need an isolated environment, KVM has your back.

If you run into issues, check the Arch Wiki — it’s one of the best resources out there.
