first of all i've now a memory image of a VM where i can reproduce it.
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?
