Subject: [PATCH v1 5/5] KVM: x86: nVMX: Ignore user space set value to MSR_IA32_VMX_VMCS_ENUM
Date: Tue, 17 Aug 2021 17:31:13 +0800 [thread overview]
Message-ID: <1629192673-9911-6-git-send-email-robert.hu@linux.intel.com> (raw)
In-Reply-To: <1629192673-9911-1-git-send-email-robert.hu@linux.intel.com>
This is actually "read-only" MSR, its value is determined by VMCS12 fields
existence.
