Comment 12 for bug 1721390

The error message here is quite generic, and simply means that a nova-compute service has not started correctly. There could be many causes.

Pride, in the logs you have posted nova-compute cannot connect to RabbitMQ. I would recommend trying to work out if RabbitMQ is working. Is the rabbitmq container up? Is there anything unexpected in 'docker logs rabbitmq' or in the rabbitmq log file in the kolla_logs volume?
