Subject: [PATCH 1/2] KVM: Expose MCE control MSRs to userspace
Date: Wed, 7 Jul 2010 14:09:38 +0300 [thread overview]
Message-ID: <1278500979-12725-2-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1278500979-12725-1-git-send-email-avi@redhat.com>
Userspace needs to reset and save/restore these MSRs.
The MCE banks are not exposed since their number varies from vcpu to vcpu.
