Hi Stackers-

I'm testing a dummy plugin which does and RPC based communication with
Quantum.

I have done this following:

[1] I have written dummy agent like DHCP agent  - Present in HOST
[2] I have written dummy_rpc_base like the db/dhcp_rpc_base.py - Present in
Controller
[3] I have written an testing method to the  db/db_base_plugin_v2.py  -
Present in Controller

But when I restart the quantum-server, I get this error:

TypeError: unbound method register_model_query_hook() must be called with

instead)

How to resolve this error?

How can I register a new plugin/agent with the quantum?

Please help me in this regard.
