Surely you must have virbr0? Not sure where virbr0-nic comes from but I assume it's created by libvirt.
virbr0's MAC is copied from the first NIC that's attached to it. To ensure that virbr0 has (1) a MAC (if no NIC's attached, it won't have a MAC) and (2) always the same MAC, virbr0-nic is created and attached to virbr0.
OK, thanks.
