Subject: [PULL 07/19] kvm/i386: Use a per-VM check for SMM capability
Date: Mon, 15 Feb 2021 14:16:14 +0100	[thread overview]
Message-ID: <20210215131626.65640-8-pbonzini@redhat.com> (raw)
In-Reply-To: <20210215131626.65640-1-pbonzini@redhat.com>

From: Tom Lendacky <thomas.lendacky@amd.com>

SMM is not currently supported for an SEV-ES guest by KVM. Change the SMM
capability check from a KVM-wide check to a per-VM check in order to have
a finer-grained SMM capability check.
