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.
