Open Stack

Hi everyone,

After completing openstack installation from the link:  http://devstack.org/
I was able to access images list from openstack dashboard but after I
restarted my machine I am getting following error:
CommunicationError at /admin/images/images/CommunicationError at
/admin/images/images/

Error finding address for

Moreover, When I run '$nova list' or any other command from terminal, I get
the following communication error:

ERROR (ConnectionError): HTTPConnectionPool(host='10.0.2.15', port=8774):
Max
retries exceeded with url:
/v2/4cb43a0df9974c9492a1501eb1b8cb56/servers/detail
 (Caused by <class 'socket.error'>: [Errno 111] Connection refused)

I tried to check the glance api service and  registry service at
http://127.0.0.1:9292 and http://127.0.0.1:9191 but got no services running
there.
Please tell me how do I fix this error? Thank you very much in advance for
any assistance or guideline.
