first of all i've now a memory image of a VM where i can reproduce it.
You mean you start that VM with -incoming 'exec:cat /path/to/vm.img'?
But google stress test doesn't report any error until you start
migration _and_ it finishes?
That sounds good enough. Can you upload the image somewhere (doesn't
have to be a public place, you can contact David or others offlist)?
reproducing does NOT work if i boot the VM freshly i need to let it run
for some hours.
Then just when the migration finishes there is a short time frame where
the google stress app reports memory errors than when the migration
finishes it runs fine again.
It seems to me it is related to pause and unpause/resume?

Another test:
- start the VM with -S, migrate, do errors appear on the destination?
Thanks,
