brctl showmacs xen-br0
if you don't see the domU's mac address you are likely hitting a bug, I
have been seeing this on and off with recent changesets on my SMP
machine.
Another new bug I just started to see is two vifs get created when
nic=1, this is related to my domU configs, in some I had mac/bridge
declared. I get two vifs, in the ones where I only specified mac I got
one vif.
xm network-list "name of domU"

Ted
