Description

This is a simple guide for getting started with virt-manager on Arch Linux.

Prepare the Environment

  • Make sure the system is up to date:
    sudo pacman -Syu
  • Install libvirt and a few dependencies:
    sudo pacman -S libvirt qemu ebtables dnsmasq bridge-utils openbsd-netcat
    • NOTE: Extra architectures can be installed by installing the qemu-arch-extra package
      sudo pacman -S qemu-arch-extra
  • Create the qemu user and added it to kvm group:
    sudo groupadd kvm
sudo useradd -MrG kvm qemu
  • Edit the qemu config:
    sudo nano /etc/libvirt/qemu.conf
    • And set the user and groups that qemu will use:
      user = "qemu" 
group = "kvm"
  • Start and enable libvirtd.service at boot:
    sudo systemctl enable libvirtd
sudo systemctl start libvirtd
  • Change the group authorized to access the RW daemon socket, create the following file:
    sudo nano /etc/polkit-1/rules.d/49-org.libvirt.unix.manager.rules
    • And add the following:
      /* Allow users in kvm group to manage the libvirt
daemon without authentication */
polkit.addRule(function(action, subject) {
    if (action.id == "org.libvirt.unix.manage" &&
        subject.isInGroup("kvm")) {
            return polkit.Result.YES;
    }
});
  • Then add the bob user to the kvm group:
    usermod -aG kvm bob
  • Log out and then log back in for the permissions to take effect.

Install virt-manager

  • Install virt-manager hypervisor:
    pacman -S virt-manager
  • Create a new QEMU/KVM Session connection
