The matrix is basically Intel ARK - oVirt, from my understanding, will set the cluster to the minimum supported set of instructions. Meaning if they are identical instruction sets across all CPU's - then nothing is lost, but if even 1 CPU in the cluster has less available features then the rest, then all will be brought down to that level so to speak. There may be some major incompatibilities im not aware of, but with at least 2CPU's in the same family, I don't think you would be losing much if any.

Hello,

In my case I currently have a cluster with hosts with cpu Intel E5-2680 v4 (each socket with 14 cores) and their Cluster is set as "Intel Broadwell Family" and I would like to add in the same oVirt Cluster two more hosts with Intel E5-2640 v4 cpus (each socket 10 cores) that should be the same CPU Family Type.

Is it true?

Is there a sort of matrix where one could compare and match?

Thanks in advance,

Gianluca
