My single node openstack devstack setup is currently running perfectly, but when I change hostname of my system i.e. I made changes in /etc/hosts and /etc/hostname to set a new hostname. After rebooting system setup is running with error of oslo messaging saying

ERROR oslo.messaging._drivers.impl_rabbit [-] AMQP server closed the connection. Check login credentials: Socket closed

On running nova list error shows up saying

ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-c4251e32-c59e-4ebf-aad1-9f13236f41a1)

Any idea what is potential solution to this.

PS: If I revert back the changes, it start running perfectly.

I'm my opinion it's related to credentials problem. Try updating the keystone entries for the particular node you made changes

Please let me the outcomes.....

Its a single node setup. So all I did was changed the hostname of my machine on which openstack single node setup is running.
