Subject RE: Problem with bridge
Date Sat, 15 Dec 2012 18:13:07 GMT
I assume inetbr0 is on VLAN, one possibility is VLAN may not be configured correctly.

Normally I do following test to verify VLAN.

Configure a IP for inetbr0 on KVM host, this IP should be on the same network with gateway.
ping gateway from KVM host
