What would be the use case? A HV starts a guest which is supposed to be
encrypted using the AMD's confidential guest technology but the HV tells
the guest that it is not running on an AMD SVM HV but something else?

Is that even an actual use case?

Or am I way off?

I know we have talked about this in the past but this still sounds
insane.
