I think we should at least try and send the dhcp request out on the
bridge that the guest's first VIF is going to attach to -- it might be
on an entirely different VLAN or even physical network from dom0.

Possibly it will work just to set the bridge as the interface that the
raw socket is bound to when sending the dhcp request.
