I would use vdi locking if there is no other way to avoid concurrent access to a single vdi. f.e. if you use sheepdog as storage and there is a (even very small) possibility that a VM is started twice (split-brain in cluster?) As far as I understand the current implementation it's not possible to use native libvirt live-migration with vdi-locking enabled, but you could of course use suspend-migrate-wake migrations.
