[ovirt-users] Change Cluster CPU type

We are using oVirt for several years. And we start with Xeon v2 CPUs. At this moment of time we got all v3 aтв we will chnage them to v4 in a month. So i would like to change Cluster default CPU to Haswell, But got error with custom cpu on HostedEngine. HostedEngine config is locked. Is there a solution to chnage HostedEngine cpu type? P.S. some problem with Cluster compability version (4.5 4.6)
