hello sunil,

please do check your /etc/nova/nova.conf in which you provided rabbitmq details like username and password by default the password will be guest make sure if you changed it then it must reflect in all other services also.

HI the issue is with your messaging service. Make sure the rabbitmq service is running fine in the controller server and its accessible from all the nodes.

You can check the status with following command : rabbitmqctl status

After that use telnet to check the connectivity to its port 5672 from other servers.

Also try turning off the firewall if any.
