Installation
NixOS
Before 23.11:
virtualisation.libvirtd.enable = true;
programs.dconf.enable = true; # virt-manager requires dconf to remember settings
environment.systemPackages = with pkgs; [ virt-manager ];
After 23.11:
virtualisation.libvirtd.enable = true;
programs.virt-manager.enable = true;
You will get a warning when you open it for the first time:
Could not detect a default hypervisor. Make sure the appropriate QEMU/KVM virtualization packages are installed to manage virtualization on this host.
A virtualization connection can be manually added via File->Add Connection
To resolve:
File (in the menu bar) -> Add connection HyperVisor = QEMU/KVM Autoconnect = checkmark Connect
The same can also be achieved declaratively by setting the corresponding dconf settings with home-manager. If you want to do this instead of the imperative configuration described above, add the following snippet to your home-manager configuration:
dconf.settings = {
"org/virt-manager/virt-manager/connections" = {
autoconnect = ["qemu:///system"];
uris = ["qemu:///system"];
};
};
You may get the following error:
authentication unavailable: no polkit agent available to authenticate action 'org.libvirt.unix.manage'
To resolve, add the user to the libvirtd group:
{
users.users.<myuser>.extraGroups = [ "libvirtd" ];
}
