Did you try to run any tracing tools (like Ethereal) to see if you
receive packets on any interfaces? Also, does "brctl show" display all
interfaces properly connected to the bridge? Does your routing table (ip
r) show correct entries?

Do you have both eth0 and eth1 configured and active with static IP
addresses? How does your ifconfig output look like when you run a DomU?
