I have a rabbitmq 3.5 server in the node controller, and despite that, on the compute node logs, it gives me an error:

ERROR oslo.messaging._drivers.common [-] ['Traceback (most recent call last): \ n", "File" /usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher. py ", line 133, in _dispatch_and_reply \ n incoming.message)) \ n", "File" /usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py ", line 185, in _dispatch \ n raise UnsupportedVersion (version) \ n ',' UnsupportedVersion: Endpoint does not support RPC Version 3.33 \ n ']

and always at the creation of a new instance, it remains in BUILD mode without being created.
