The public interface, I thought was the interface of the DomU running the service, and it attached its own bridges inside the DomU?
I have tried to describe all this here: http://wiki.openstack.org/XenServer/NetworkingFlags Would be cool if people can check that for me, and I can push it into the manuals.

I would suggest public_interface=xenbr0 Xen experts, please correct me if I'm wrong. flat_interface=eth0 flat_network_bridge=xenbr0
