I'm more interested in seeing what type of corruption is happening;
if you've got a test VM that corrupts memory and we can run a program
in that vm that writes a known pattern into memory and checks it
then see what changed after migration, it might give a clue.

But obviously this would only be of any use if run on the VM that actually
fails.
