[ovirt-users] Re: Host affinity hard rule doesn't work

Try disabling or making the VM rule soft, it won't migrate more than one VM at a time so it can't migrate either VM without breaking the vms_rule.

Create an affinity group as below: VM affinity rule: positive + enforcing Host affinity rule: disabled. VMs: 2 VMs added Hosts: No host selected. 2. Run the 2 VMs, they are running on the same host, say host1. 3. Change the affinity group's host affinity: Host affinity rule: positive + enforcing Hosts: host2 added. I expect that the 2 VMs can migrate to host2, but that never happen, is this expected? snippet of engine.log: 2019-03-13 07:47:05,747Z INFO [org.ovirt.engine.core.bll.scheduling.SchedulingManager] (EE-ManagedThreadFactory-engineScheduled-Thread-30) [] Candidate host 'dub-svrfarm24' ('76b13e75-d01b-4dec-9298-1fad72b46525') was filtered out by 'VAR__FILTERTYPE__INTERNAL' filter 'VmAffinityGroups' (correlation id: null) 2019-03-13 07:47:05,747Z DEBUG [org.ovirt.engine.core.bll.scheduling.arem.AffinityRulesEnforcer] (EE-ManagedThreadFactory-engineScheduled-Thread-30) [] VM 822b37b7-5da3-453c-b775-d4192c2fdcae is NOT a viable candidate for solving the affinity group violation situation. 2019-03-13 07:47:05,747Z DEBUG [org.ovirt.engine.core.bll.scheduling.arem.AffinityRulesEnforcer] (EE-ManagedThreadFactory-engineScheduled-Thread-30) [] No vm to hosts soft-affinity group violation detected 2019-03-13 07:47:05,749Z DEBUG [org.ovirt.engine.core.bll.scheduling.arem.AffinityRulesEnforcer] (EE-ManagedThreadFactory-engineScheduled-Thread-30) [] No affinity group collision detected for cluster 8fe88b8c-966c-4c21-839d-e2437cc6b73d.
