It can be used for UUID generation when VM is started for the first time.
Management application can retrieve UUID using monitor and use it for
consequent runs. But the same result can be achieved in a different way
too. So no, I really don't have a strong use case for this feature, but
the patch set is organised in such way that it is possible to ignore
this particular patch.
