While configuring the compute node , When I restart the services , nova-api is not starting. Further when I use the command "*nova image-list*". It returns "*ERROR (ConnectionError): ('Connection aborted.', error(111, 'Connection refused'))*.

Here are some outputs, which may help to diagnose the issue:

root [at] controller:service nova-api restart* stop: Unknown instance:

nova-api start/running, process 4278

root [at] controller:ps -eaf | grep "nova-api"* root 1000 4306 1670 15:20 pts/1 00:00:00 grep --color=auto nova-api
