Hello,

I am a user of oVirt Engine 3.6.2.6-1.el7.centos .
Ovirt 3.6 still has a bug that classifies IvyBridge CPU(i7-3770K) as
Westmere and clusters it.

Is this bug fixed in ovirt 4.x?

and
Is there a prospect of correcting this bug in ovirt 3.6?

When IvyBridge is added to cluster of SandyBridge, an error of CPU_TYPE_INCONPATIBLE_WITH_CLUSTER appears.
