DNS lookup worked fine until I setup network bridge. How to repair it?

Verify your default route still exists after the bridging. It's dumped when the interface goes down and then up. –  DrGkill Aug 30 '11 at 11:02

Also, your eth0 should not have an IP configuration. Modify your network config to disable eth0 configuration. –  sybreon Aug 30 '11 at 11:56
