This was initially motivated by a KubeVirt issue[1] concerning
integration with the Portworx storage provide, but it turns out to be
more generally applicable: since mounting an NFS share on the same
host that is exporting it is known to cause issues and is therefore
not recommended, we need a way to allow migration in such a
configuration while still not going quite as far as
VIR_MIGRATE_UNSAFE does and losing all handrails.

but please add some wording being more explicit about the need for the
storage to be still shared. While it's implied in all places users tend
to ignore any non-obvious messaging.
