Ok, I see it, thanks for explaining.
So back to your original ideas - I'm wondering whether we should define
a chunk of memory which the hypervisor and guest can share and thus
communicate over... Something ala SEV-ES also with strictly defined
layout and put all those variables there. And then the guest can map
decrypted.
There might be something similar though, I dunno.
Maybe Paolo has a better idea...
