Hi, I'm new to Nova and would like to clear up some issues.

The Nova's compute node networking configuration creates the default bridge
(br100), copying eth0 values and connecting the actual eth0 along with the
VMs. Xen does almost that, it renames the physical eth0 to peth0 and creates
a bridge named eth0 that connects the VMs and peth0.

Could Nova work using the Xen's eth0 bridge? I think if it was the old
'"xenbr0" bridge it could be easier just to change the bridge name in the
DB, but how does that work even with the controller not habing Xen installed
(so eth0 would be the real interface)?

Also, in the Administrator's Manual, it says that you need KVM + libvirt for
live migration, would Nova work with Xen for live migration?

Thanks!
