Nova connects to RabbitMQ through the defaults values (
localhost:5672) and credentials (guest)<br>
Check for the address of your rabbitMQ in the config file
(/etc/rabbitmq/rabbitMQ.config)<br>
<br>
and do this <br>
nano /etc/rabbitmq/rabbitmq.config<br>
[{rabbit, [{tcp_listeners, [{"127.0.0.1",5672}] }] } ]. #Paste this
line<br>
#Exit and SAVE<br>
service start rabbitmq-server<br>
<br>
This certainly will make your rabbitMQ talk to Nova. otherwise there
is something wrong with your nova<br>
