The access controls with libvirt are done using Policy Kit,
http://libvirt.org/auth.html. However I don't think it's fine grained
enough to limit access per guest.
Maybe instead of giving each user access to their guest via the
management host, you give them access to the guest itself not the
host. Something like XDMCP. That will give them a desktop session on
the VM. You can then lock down the virtual host and open up access to
only the guests. I've used this setup before in situations when I
needed to see a desktop remotely...
