Ah right thanks! However, it's a hack to get around the real problem
with libvirt. Not to mention that the output from virsh dumpxml is
where you have to cover your eyes and try not getting sick while
editing :(

Having a normal config file in readable format where you could add
regular command line options manually would make life so much easier.

Cheers,
