Public bug reported:
Some MechanismDrivers need their own RPC backend that can be used by an
agent to talk to this driver. When running in uwsgi/rpc mode we need to
make sure these RPCs listeners are started as part of the neutron-rpc-
server. Currently this is only done for service plugins, but
MechanismDrivers are part of the Ml2Plugin (which is itself a service
plugin).
To allow drivers to start their own RPC listener I propose that the
ML2Plugin takes care of this. Ml2Plugin can call
MechanismManager.start_driver_rpc_listeners(), which then calls
start_rpc_listeners() on each MechanismDriver. The resulting server
plugins could then also be returned as part of
Ml2Plugin.start_rpc_listeners().
I have a PoC for this running in my dev environment and if we agree on a
rough concept would be willing to provide a patch for this.
