I am seeing these messages in noa-api.log file, and the nova is notfunctional in dashboard. I believe the problem is with rabbitmq, but idon't know how to solve this situation.

Nova connects to RabbitMQ through the defaults values ( localhost:5672)and credentials (guest)Check for the address of your rabbitMQ in the config file(/etc/rabbitmq/rabbitMQ.config)


and do this
nano /etc/rabbitmq/rabbitmq.config
[{rabbit, [{tcp_listeners, [{"127.0.0.1",5672}] }] } ]. #Paste this line
#Exit and SAVE
service start rabbitmq-server

This certainly will make your rabbitMQ talk to Nova. otherwise there issomething wrong with your nova
