Description
SVM requires that EFER.SVME remain set in order enter guest context. Without shadowing said value, it will be visible to the guest that SVM is enabled, despite the fact that we will not permit them to do nested virtualization. It would be better to trap accesses to EFER to hide the existence of SVME. Doing so would match the behavior of KVM.
