Try this :
- make sure iptables is disabled, and check again
- ifconfig eth0 down
- ifconfig xenbr0 up

Try pinging the gateway. If it works, probably there's a bug in
netloop module. You can try earlier kernel version ( < 2.6.18-128 ),
and file a bug to Centos.

Another alternative is to setup bridging from the OS, not using Xen's
bridge script (which is what I have in my setup).
