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.
