This is functionality we are actually missing for ovirt as well.  I had done a
proof of concept patch a while ago (you can search the libvirt archives), but it
wasn't comprehensive enough.  In particular, it could deal with putting a
physical device into a bridge, but didn't make any provision for bonding and
VLANs, both of which are needed to have a correct solution.  It needs some
thought about the XML design, and then it can probably be implemented.
