[ovirt-devel] disk cache issues

Hi, After digging around and finding a bit of info about viodiskcache - I understand that if the user enable it - then the VM cannot be live migrated. Umm, unless the op decides to do a live migration including changing storage - I don't understand why the live migration is disabled. If the VM will only be live migrated between nodes, then the storage is the same, nothing is saved locally on the node's hard disk, so what is the reason to disable live migration? Thanks, Hetz
