Description Arik 2021-07-04 13:25:57 UTC 
We currently pin vCPUs automatically when adding/updating the virtual machine based on what of the hosts that the VM is pinned to (under the assumptions these hosts are the same).

This RFE is about doing it based on the host that the VM is going to run on and it only applies to the 'Resize and Pin' policy.

verified in ovirt-engine-4.5.0.5-0.7.el8ev.noarch
on the base of the attached RHEVM3/wiki/Compute/4_4_auto_pinning Part 3. Part 1&2 still need to be refactored according to the changes in this feature (deprecating adjust and existing)
