Yes, in fact I suggested that ASID should be in svm->asid and moved to svm->vmcb->asid in svm_vcpu_run. Then there's no need to special case it in nested code. This should be a patch coming before this one. > > 1.

In general I think it's better to be explicit with vmcb01 vs. vmcb02, like Cathy did, but I can see it's a matter of personal preference to some extent. Paolo
