When 4.4.3 was released it was reported several times to the list that also a 4.5 option for the cluster level had appeared.

And it was answered that this specific version (its logic seemed quite strange to me indeed) would have been dedicated to linux nodes in RH EL 8.3 or CentOS 8.3 or RHVH/ovirt-node-ng built on top of this version.

Now my 3 nodes are all in CentOS 8.3 but no selection is possible.

I heard Sandro off the list and I think in a short time he or someone else through the developers will answer more precisely about this.
