[PULL 07/19] kvm/i386: Use a per-VM check for SMM capability

Posted by Paolo Bonzini 4 years, 10 months ago

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.
