hii

i am new to openstack and i have installed the openstack cloud in ubuntu server 14.04.

I installed the nova package on the controller node and i tried to check the nova image-list it is giving an error

sunny@controller:~$ nova image-list ERROR (CommandError): You must provide a username or user id via --os-username, --os-user-id, env[OS_USERNAME] or env[OS_USER_ID] sunny@controller:~$

and the status of the service is as follows sunny@controller:~$ service nova-api status nova-api stop/waiting sunny@controller:~$

when i tried to restart the nova-api service it is starting and again after few seconds it is going to stop/waiting state and from the nova-api logs i found this
