libvirt users - Jul 2011 - UID/GID for qemu & kvm

We use AD infrastructure for user/group management, and GID 107 is already in
use.  Can I create an AD entry for the kvm and qemu groups with different GIDs,
as well as the qemu user/UID?  From looking at the libvirt package, it appears
it does a getent to see if these exist and, if not, creates them locally, so I
assume adding them to AD is ok - and that the GID/UID specified in the package
isn't explicitly necessary.  Just looking for verification.
