Subject: [PATCH 5/5] KVM: nVMX: Simplify the initialization of nested_vmx_msrs
Date: Fri, 28 Aug 2020 16:56:22 +0800 [thread overview]
Message-ID: <20200828085622.8365-6-chenyi.qiang@intel.com> (raw)
In-Reply-To: <20200828085622.8365-1-chenyi.qiang@intel.com>
The nested VMX controls MSRs can be initialized by the global capability
values stored in vmcs_config.
