Cool!
How does this interact with migration? If a domain is currently marked
autokill on the source, should that mean that attempts to migrate it are
forbidden (since the connection to the source would end up being useless
after the migration, at which point the connection is gone and autokill
should kick in)?
That's a good point. I reckon we should forbid migration and save/restore
for such guests.
