Hi,

I am writing a Compute Node Simulator.
The idea is that I would write a piece of software using C which honors the RabbitMQ interface towards the Controller, but will not actually do the real thing - everything on the Compute Node will be simulated by my simulator software.

The  problem I am facing, that I have not been able to get my simulated CN listed in the output of
nova-manage service list

I am on Havana, and my simulator is sending a periodic  'service_update' and 'compute_node_update' RPC messages to the 'nova' exchange and the 'conductor' routing key.
I can manipulate the above messages at will to fool the controller.
(I observe the messages from a real CN and take cues from there to construct a fake one from my simulator)

Question is - what causes the controller to add a new Nova Compute in its database, is it the 'service_update' RPC or something else.

Hopefully you can help me reverse engineer the interface.

Regards
-Prashant
