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.

Cheers,
John

If you want all your traffic going through a single nic (Management, Instance, Public), it might be possible using these settings:

public_interface=eth0

I don't think this will work unless the implementation is very different in xen.  xenbr0 will be bridged into eth0, so you actually want to be adding ips to the bridge not the raw eth device.  I would suggest

public_interface=xenbr0

Xen experts, please correct me if I'm wrong.


flat_interface=eth0
flat_network_bridge=xenbr0
