Hmm, yes, this proposal doesn't really cover migration does it...
You obviously can't migrate with a device passed through but it should
be possible to unplug, migrate and replug. Maybe having a sensible hole
on the first host is sufficient... Especially if the annoying case is
GFX passthrough -- you are much less like to want/be able to unplug your
gfx over a migration...
Ian.
