And it's not really needed: the traffic you want is present on at last
one ethernet interface (virtual or real) as the traffic accross the
bridge has to come from somewhere (and eventually goes somewhere).
So just run tcpdump on the right interface. To capture a domU traffic,
run tcpdump on the corresponding xvifx-y interface in dom0.
