Within oVirt or on the command line as I created the first data volume when I installed oVirt from scratch? I guess the former should work, right? But then, can I do live migrations from the lower CPU cluster to the newer one? I guess it's possible according to this: http://www.ovirt.org/develop/release-management/features/storage/live-storage-migration-between-mixed-domains/ Thanks for your time -- Davide Ferrari Senior Systems Engineer
