Open Stack

I have read it
https://docs.openstack.org/masakari/xena/install/overview.html
I tested with two segments but It dont have my desired result.
Segment A:
 compute01
 compute02
 compute03
Segment B:
 compute04
 compute05


When I turn off compute01, I hope that instance will recover on compute02
or compute03 but it recovered on segment B.
I feel strange.
