Guess I hadn't thought that far. 'controlled' above is probably not the
right
wording. 'safeguard' may be the better one. Was mainly thinking of a
mechanism
that would prevent the initial cluster from starting the vm again if
something
goes wrong with the sequence of actions described.
But of course the idea of using booth to actively trigger a migration sounds
appealing and generally useful.
Maybe something to put on the wishlist ;-)
