Re: Problems connecting Dashboard and Nova

 

A patch to nova.sh actually went in recently to detect this problem instead of accidentally generating a bunch of screens, but it isn't in a lot of the derivative versions.  When I used to get into this situation, a simple:
sudo killall screen
usually works fine (assuming there are no other important screens running)

You'll need to kill all of those sessions.  since you have so many, I'd suggest just rebooting the machine to clear them out, otherwise you can screen -r <screenname> for each screen, where screenname is 30040.nova, etc, and exit the bash process that's running in them.

The dashboard only supports                                                         Keystone based authentication right now, and it looks like you're trying to connect to nova using Nova's                                                         builtin auth.  That howto you are following is quite old.   If you're looking to get openstack up and running on a single box, you might want to try this script (https://github.com/4P/deployscripts/blob/master/nova.sh) which sets up nova+keystone+glance+dashboard on a single host.
