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.
