Subject: [PATCH] x86/kvm/hyper-v: don't announce GUEST IDLE MSR support
Date: Thu, 24 Jan 2019 15:27:09 +0100 [thread overview]
Message-ID: <20190124142709.8184-1-vkuznets@redhat.com> (raw)
HV_X64_MSR_GUEST_IDLE_AVAILABLE appeared in kvm_vcpu_ioctl_get_hv_cpuid()
by mistake: it announces support for HV_X64_MSR_GUEST_IDLE (0x400000F0)
which we don't support in KVM (yet).
Fixes: 2bc39970e932 ("x86/kvm/hyper-v: Introduce KVM_GET_SUPPORTED_HV_CPUID")
