Don't think so, since we'll continue to run old guests as pure PV.
There was a backup for running on older CPUs, and that was to allow PVH
guests to run on shadow page tables. That's a totally separate compatibility
concern however.

Yes, but it's auto-xlat in an HVM container. Pure PV auto-xlat is what we're
looking to kill here.
