One more I should mention:
4) After encryption, the page table is no longer usable for translations by
stuff like addr_gva2gpa(), so tests would either need to be

cached/stored values thereafter, or perhaps a "shadow" copy could be
maintained by kvm_util so the translations will continue to work
after encryption.
Yeah, this is a big one. Considering that a lot of the selftests are
for specific bugs, the benefit in running them with SEV is relatively
low. That said, there could be some simple tests where it makes sense,
so it'd be nice to plan a little ahead so that it isn't _too_ difficult.
