Open Stack

"screen -x stack" should give you the clue as to why it's failing. In my
case it printed

2013-11-07 23:24:14.758 TRACE nova IOError: [Errno 13] Permission denied:
'/etc/nova/api-paste.ini'
2013-11-07 23:24:14.758 TRACE nova
n-api failed to start

all i had to do was change the ownership of the files to the user executing
stack.sh and restart the process.
