The nova create-server API allows passing a network id that's prefixed with br-<uuid> [1]. That was added due to this bug from Folsom [2]. I'm wondering if that's still valid? Looking at the network.id data model in Neutron it doesn't look like it would be [3]. I'm trying to sort this out for the get me a network spec in nova [4] because as part of the jsonschema validation change for that microversion, I was going to require that network ID be a uuid, or the special 'auto' or 'none' values. Supporting br-<uuid> type IDs would mess that up.
