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? > Thanks, > michal > > > > > Michael, can you take a look at http://gerrit.ovirt.org/22129 and advise? > > > > > > -- > > Sandro Bonazzola > > Better technology.
