I'm not sure if > NM is going to do things with interfaces you created through ip. For VMs, these interfaces are created by Xen's toolstack when the VM is started and destroyed by Xen's toolstack when the VM is destroyed; generally speaking all that's needed is for them to be plumbed into the bridge with the right mac address. The guest then does all of its own DHCP &c. As long as that can be done via `ip`, there's nothing NM really needs to do. -George
