Thus, Live Migration gives the following error: "Live Migration failure: Unsafe migration: Migration may lead to data corruption if disks use cache != none" However, it is ok to migrate if the storage is "coherent" across nodes. So Nova's live-migration should support the Libvirt's unsafe=True flag. Ideally there should be a nova flag which can be set to pass through the libvirt 'unsafe=true' flag. My thinking is that if 'cache=writethrough' is set then the underlying storage should be safe, but perhaps it's best not to make that assumption and rather to have a nova.conf flag.
