I think I agree. It would be easy if we were to just loop until the
domain gets unpaused but that's not really quite the correct fix, since
we ideally want 'xm save' to fail cleanly if the domain is paused (I
vaguely remember seeing a patch for this go past?).

Maybe a xenstore entry for the domain which is written just after the
.unpause() (the absence of this would also prevent xm pause, xm destroy,
perhaps)
