Got it to run with mysql. Now, the multi-session screen doesn't come up, it
says:
+ screen -S nova -X screen -t n-api
There are several suitable screens on:
    30040.nova    (08/09/2011 06:36:19 PM)    (Detached)
    29522.nova    (08/09/2011 06:10:17 PM)    (Detached)
    28011.nova    (08/09/2011 05:31:30 PM)    (Detached)
    27686.nova    (08/09/2011 05:30:07 PM)    (Detached)
    27369.nova    (08/09/2011 05:27:09 PM)    (Detached)
    27269.nova    (08/09/2011 05:03:46 PM)    (Detached)
    26985.nova    (08/09/2011 02:58:43 PM)    (Detached)
    26911.nova    (08/09/2011 02:55:58 PM)    (Detached)
    26839.nova    (08/09/2011 02:54:42 PM)    (Detached)
Use -S to specify a session.

Thanks Arvind,

Mauricio
