[ovirt-users] Windows 7 to 10 Upgrade fails

I'm trying to update some Windows 7 VMs before the free upgrade period ends. It appears Windows 10 has an issue with KVM during the upgrade, and according to this thread, http://ubuntuforums.org/showthread.php?t=2289210&p=13334367#post13334367 , you need to specify the CPU type as core2duo for the VM, perform the upgrade, then switch it back. Is there anyway with ovirt to set the CPU type to core2duo for a single VM without having to shutdown the entire cluster, change it for the cluster, do the upgrades, then change it all back? Thank you
