KVM, or Kernel-based Virtual Machine, is a powerful virtualization technology in Linux that allows you to run multiple virtual machines on a single host machine. In this tutorial, we will guide you through the process of installing KVM on your Arch Linux machine.
Before you start, make sure you have the following prerequisites:
To use KVM on your Arch Linux machine, you need to install the necessary packages. Open the terminal and run the following command:
sudo pacman -S qemu virt-manager libvirt ebtables dnsmasq bridge-utils openbsd-netcat
After installing the above packages, enable and start the libvirtd service using the following commands:
sudo systemctl enable libvirtd
sudo systemctl start libvirtd
To check if KVM is installed and configured correctly, run the following command:
lsmod | grep kvm
If the output shows kvm and kvm_intel or kvm_amd, it means that KVM is successfully installed on your Arch Linux machine.
By default, the libvirt group has access to the VMs managed by libvirtd. Therefore, add your user to the libvirt group using the following command:
sudo gpasswd -a ${USER} libvirt
Finally, you can install the guest OS of your choice using the virt-manager GUI or command-line tools, such as virt-install.
For example, to install the Ubuntu guest OS, use the following command:
sudo virt-install --name ubuntu --ram 2048 --disk path=/var/lib/libvirt/images/ubuntu.img,size=20 --vcpus 2 --os-type linux --os-variant ubuntu20.04 --network network=default --graphics vnc --console pty,target_type=serial
By following these steps, you can easily install KVM on your Arch Linux machine and start using it to create and manage virtual machines. Happy virtualizing!
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
