[ovirt-users] Host affinity hard rule doesn't work
Hi there,
Here is my setup:
oVirt engine: 4.2.8
1. 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?
