Description of problem:
When power saving balancing policy is used, vm's still migrate between two hosts.

Version-Release number of selected component (if applicable):
is13

How reproducible:
always

Steps to Reproduce:
1. Create cluster with 3 hosts and power saving policy (High 75%, low 20%)
2. Load hosts:
   host1(hsm1): 25% (1 running vm)
   host2(hsm2): 50% (2 running vms)
   host3(spm):  75% (3 running vms)

Actual results:
one vm still migrate between host2 and host3.

Expected results:

Ondra,
This is working by design.
On power saving VMs migrate to the busy hosts to make other hosts free to shut down.
