* As per discussion with Janis and Claudio, remove the actual access check from

* Typos/Style suggestions (thanks Janis)

Upon migration, we expect storage keys set by the guest to be preserved,
so add a test for it.

We keep 128 pages and set predictable storage keys. Then, we migrate and check
they can be read back.
