we decided it'd be more flexible for RHV if we had a way to map
individual NICs to target networks and bridges. This can be done by
adding a new --mac option so you can specify the exact mapping you
need:
$ virt-v2v [...] \
--mac 52:54:00:d0:cf:0e:network:mgmt \
--mac 52:54:00:d0:cf:0f:network:clientdata
