Hold on a sec though...

Is this a matter of

can boot from a guest firmware that doesn't pre-validate all the
guest memory?

or

can boot from a guest firmware that doesn't pre-validate all the
guest memory ... with access to all of that guest's RAM?

In other words, are we talking about "fails to boot" or "can't see all
the RAM"?
