This all looks good, and simply adding the vmuuid argument to the
callchain that goes down to virNetDevOpenvswitchAddPort seems like the
simplest, most consistent way to get the information down to that function.
ACK, and pushed.

Hmm. I just now noticed the odd indentation here. I'll take care of that
in a separate small patch.
I'm also sending a patch to call virReportOOMError() when the
virAsprintf() calls in that function fail.
