Hello Tracy,

some of the problem I faced, to execute different nova cli(s), i required
to restart nova service every-time.

Nova service needs to fully start/realize, before debugging can start.

import pydev; works as break-point for debugger, needs to add at all the
places.

For ex: in case one wants to debug nova boot flow end-to-end.
            needs to know, the exact code location to put break-point in
each service.


Regards,
Yatin
