<br>Define "like". ;)
<br>
<br>I run tcpdump on vnet0, I see arp requests coming from the instance. I
<br>run it on br100, I don't see anything coming from the instance.
<br>
<br># brctl show br100
<br>bridge name bridge id STP enabled interfaces
<br>br100 8000.003048c53032 no eth0
<br> vnet0
<br>
<br>(I think I did "brctl addif br100 vnet0" manually at some point, it
<br>didn't make any difference.)
<br>
<br>brctl showmacs does not include guest's mac.
