Doc Text:	This feature adds rule enforcement support for VM to host affinity. VM to host affinity groups require the affinity rule enforcer to handle them in addition to the existing enforcement of VM to VM affinity. The rule enforcer will now be able to find VM to host affinity violations and choose a VM to migrate according to these violations.	Story Points:	---

Description Martin Sivák 2016-12-14 11:38:56 UTC

+++ This bug was initially created as a clone of Bug #1392393 +++

Certain set of VMs form a logical management unit and should run on a certain set of hosts for SLA or management (e.g. a separate rack for each customer). The VMs can run anywhere in case the dedicated rack needs to be turned off, but should return to their dedicated hosts once the rack is back up.

This would be best implemented by enhancing the current VM to VM soft affinity rules to support hosts as well. The other piece that is needed is to add affinity based balancing operation to allow the VMs to return to the proper host when it becomes available.

Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.

The merged patch was not the only one that needs to get in.

Additional patches will be added.
