Comment 19 for bug 1599836

I don't know if there is anything to be done in nova to address this. As long as the networking-baremetal plugin is used in neutron, this isn't a problem. (Is that a temporary solution or *the* solution, that is the question!) I'm going to close this for now.

We have it documented in ironic: https://docs.openstack.org/ironic/latest/admin/multitenancy.html#flat-network-interface.
