Open Stack

Hi All,

The devstack document doesn't explain how to start/stop services,
maybe it's obvious for the devstack developers but not for a new user
like me!  I can't use  commands like "restart nova-api" because they
are not installed.

I installed OpenStack using devsatck stack.sh script
(http://devstack.org/) on Ubuntu 11.10. Installation was successful
and I was able to login to Dahsboard; but it doesn't work anymore, I
think after I changed the IP address of the machine and moved it to
another network.
Apache2 is running but the nova and keystone services are not running.

Can any one please explain how to start/restart/stop all the services
after installing devstack?
This should be added to the devstack documents.

Thanks

Joe
