Maybe I do not get your scenario completely.
Would a OVN nework per host solve your problem?
OVN allows to create an isolated network that speads across the while cluster.
If I understand correctly, Brian has more humble requirement, which users implement by creating a dummy0 device (note the lack of underscore in the name). The dummy device would she as a nic on the host, allows attaching a bridge to it, but lets no traffic leave the host.
