[PATCH v8 5/8] KVM: x86: SVM: Prevent MSR passthrough when MSR access is denied

2020-09-25 Thread Alexander Graf
We will introduce the concept of MSRs that may not be handled in kernel space soon. Some MSRs are directly passed through to the guest, effectively making them handled by KVM from user space's point of view. This patch introduces all logic required to ensure that MSRs that user space wants
