 Mihai, I am putting the list here as well...

 No I didn't add the [placement] section in nova.conf on the controller 
 but adding it only on the compute node brought it online.

 I don't know yet if I can spawn an instance and if what you are saying 
 is mandatory in Ocata in order to spawn one since I haven't reached that 
 part of the installation guide. The verification though of the compute 
 services went OK as supposed to by the installation guide.

 Best,

 George
