  I guess this could happen yes.

  You would need the name or UUID, yes to then do a lookup

  In theory, yes. In practice we can't change an existing API,
and that assumes the given hypervisor used at that point will give
the information back. The format for the save are hypervisor specific
(though there is some talks of convergences) but in any case the
UUID and name informations are embedded in the file, whether it's feasible
to extract the informations and add an API is a bit unclear but I guess
that should be feasible generally by just looking at the first blocks of
the data.
