Subject: [PATCH 2/2] KVM: selftests: Don't probe KVM_CAP_HYPERV_ENLIGHTENED_VMCS when nested VMX is unsupported
Date: Wed, 10 Jun 2020 15:58:47 +0200	[thread overview]
Message-ID: <20200610135847.754289-3-vkuznets@redhat.com> (raw)
In-Reply-To: <20200610135847.754289-1-vkuznets@redhat.com>

KVM_CAP_HYPERV_ENLIGHTENED_VMCS will be reported as supported even when
nested VMX is not, fix evmcs_test/hyperv_cpuid tests to check for both.
