Thanks for that Mahardhika,

I believe you but I still don't see where this options is specified. Could
you tell me where can I find it? (I'm working on Grizzly now)
And another question: How can I configure quantum (because (correct me if
i'm wrong) it is responsible for choosing compute node for instances) to
distribute instances among compute nodes?

Any links with some explenation about that issue will be appreciated.
Unfortunately doc.openstack.org doesn't explain a lot about that.

Regards
Piotr
