Subject: [PATCH 1/5] KVM: nVMX: Fix VMX controls MSRs setup when nested VMX enabled
Date: Fri, 28 Aug 2020 16:56:18 +0800	[thread overview]
Message-ID: <20200828085622.8365-2-chenyi.qiang@intel.com> (raw)
In-Reply-To: <20200828085622.8365-1-chenyi.qiang@intel.com>

KVM supports the nested VM_{EXIT, ENTRY}_LOAD_IA32_PERF_GLOBAL_CTRL and
VM_{ENTRY_LOAD, EXIT_CLEAR}_BNDCFGS, but they doesn't expose during
the setup of nested VMX controls MSR.
