There is REC_TYPE_VERIFY, which will re-transmit all memory of a paused domU
and compare what was previously transferred. Last time I used it a large number
of pages are different. I did not spent time to dig further into it, what pfns
are affected, how the pages differ. I suspect the backends do still write into
the granted pages, hence the question.
I think the domU may undo all grants during its suspend anyway, that is
something to explore as well.
