Hi Shashi,
1. check for the below..
root at openstack:/# cat /etc/rabbitmq/rabbitmq.conf
[
{rabbit, [
{tcp_listeners, [{"0.0.0.0",5672}]}
]}
]
2. restart rabbitmq service & check below
root at openstack:/# service rabbitmq-server status
Status of node rabbit at openstack ...

This should solve the issue.

I am seeing these messages in noa-api.log file, and the nova is not functional in dashboard. I believe the problem is with rabbitmq, but i don'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 is something wrong with your nova
