That is needed for the PPC > support. Roy, we talked about it recently, where are we with this patch. We already support modifying the CPU level of an existing cluster. If changing it to a higher level then we just change it. If changing it to a lower level, and there are running VMs on the cluster, then we warn the user that some VMs might not be migrate-able, as we added a scheduling filter to filter out hosts with improper CPU level. Unless I'm missing something, that covers the use-case, isn't it?
