Open Stack

 All,

 I am setting up a new Ocata installation and although no instances are 
 running or at least not shown neither in Dashboard nor in CLI using the 
 "nova list" command I am getting a "Quota Exceeded" error.

 Why is this happening and how can I clean it up in order to continue 
 using it?

 The only thing that I can think of is that I 've tried to spawn several 
 (maybe 10) instances that went in "Error" state with "No valid hosts 
 found" error message. Apparently I 've delete the instances afterwards 
 but maybe these instances are the ones that have hang-up.

 Any help much appreciated!

 All the best,

 George
