Description Artyom 2015-08-09 13:18:25 UTC 
Description of problem:
No affinity balancing of vms that placed in the same hard, negative affinity group

Version-Release number of selected component (if applicable):
ovirt-engine-3.6.0-0.0.master.20150804111407.git122a3a0.el6.noarch

How reproducible:
Always

Steps to Reproduce:
1. Add two hosts
2. Add two vms
3. Start vms on the same host
4. Add two vms to the hard, negative affinity group
5. Wait until affinity balancing will move one of vm to another host

Actual results:
Vms still placed on the same host, and I do not see any exceptions in engine log

Expected results:
One of vm must be moved to another host

Additional info:
I do not see any exceptions under engine log, but if you will need it anyway, leave me needinfo

Created attachment 1060747 [details]
engine log

After additional investigation with Roy, found that balancing happen just first time after engine restart and after first migration balancing stop work.
Comment 2 Tomer Saban 2015-08-16 10:26:40 UTC 
There has been a logical issue in the method checkIfCurrentlyMigrating. So I added a patch that fixes it.
Comment 3 Artyom 2015-09-21 12:22:47 UTC 
Verified on rhevm-3.6.0-0.16.master.el6.noarch
Comment 4 Roman Mohr 2016-01-19 10:28:48 UTC 
Was never part of an official release and was completely reimplemented.
