We're unable to reproduce in a clean environment.
Please provide a reproducer with its relevant log files in a clean environment.
Please state the load (memory and cpu) and the destination machine.

Bug #1467063 contains everything you've asked, logs and everything.
Reproduction steps also mentioned within the original bug, e.g.

1.Clean deployment of SHE over NFS+addition of one or two NFS data storage domains on pair of ha-hosts.
2.Ensure you're running SHE VM on SPM ha-host.
3.Migrate SHE-VM to none-SPM.
4.Migrate SHE-VM back to SPM ha-host and run monitor hosted-engine --vm-status from CLI.
5.During migration of SHE-VM to SPM you expected to catch the score penalty being dropped to by 50 points due to migration retry.

Puma 18 was the SPM host.

Comment 10 Doron Fediuck 2017-08-09 13:15:39 UTC
According to the engine logs the HE VM maanaged to migrate to the SPM host:
2017-07-02 07:03:15,175-04 INFO  [org.ovirt.engine.core.vdsbroker.vdsbroker.FullListVDSCommand] (DefaultQuartzScheduler5) [601534c9] START, FullListVDSCommand(HostName = puma18.scl.lab.tlv.redhat.com, FullListVDSCommandParameters:{runAsync='true', hostId='4962ca54-b194-40c5-99fd-01a402cc9ecd', vmIds='[5d543bb5-edfe-4414-a507-c06ea2d25368]'}), log id: 75ba1ffc

And it also failed in the middle of migration, so there was a re-try and thus due to that re-try score was dropped by 50 points, then it was raised back to 3400, once re-try succeeded.
This bug is about re-try and what caused it.

Comment 15 Nikolai Sednev 2017-12-12 11:44:07 UTC
Tested on cleanly deployed ovirt-hosted-engine-setup-2.2.1-0.0.master.20171206172737.gitd3001c8.el7.centos.noarch with ovirt-engine-appliance-4.2-20171210.1.el7.centos.noarch, over Gluster storage and with one NFS datat storage domain.
Original issue was not reproduced, hence moving to verified.
