Unfortunately, the domain XML is created by the OpenShift installer,
over which I have no control.  :-(

Digging into the libvirt source, it doesn't look like there's any way
to configure MAC address generation.  I'm now investigating whether I
can mangle the source MAC of the outgoing DHCP packets with ebtables.

Uugh.
