In principle, you could actually initialize a TDX guest with all of its
memory shared and all of it mapped in the host IOMMU.

Not sure how this works in TDX, but in SEV code fetches are always
treated as encrypted. So this approach would not work with SEV, not to
speak about attestation, which will not work with this approach either
:)

Oof.
