That doesn't make sense, we know that and SEV-ES guest can't cope with extra #VC exceptions, so there is no point in testing this. It is more a way to shot oneself into the foot for the user and a potential source of bug reports for SEV-ES guests.

I think SEV-ES guests should only have the intercept bits set which guests acutally support.
