Have you tried this ?
```nix
{ config, pkgs, ... }:
{
virtualisation.libvirtd.enable = true;
users.users.myuser.extraGroups = [ "libvirtd" ];
}
```
This should seamlessly integrate with other options. By default
lists will be concatenated, not overwritten.
No I didn't. I was assuming that the lists would conflict. I tried it
and it works. (Obviously my nix understanding is still being formed.)

I have looked in the nixos manual (not to be confused with the nix
manual, or the nixpkgs manual), searching for soe text describing this
behavior.
I found http://nixos.org/nixos/manual/index.html#sec-modularity. It says
(amongst other things)
Note that both |configuration.nix| and |kde.nix| define the option
|environment.systemPackages|. When multiple modules define an
option, NixOS will try to /merge/ the definitions. In the case of
|environment.systemPackages|, that’s easy: the lists of packages can
simply be concatenated. [...]
