Subject: [PATCH 0/2] Fix MCE not cleared on reset
Date: Wed, 7 Jul 2010 14:09:37 +0300 [thread overview]
Message-ID: <1278500979-12725-1-git-send-email-avi@redhat.com> (raw)
Injecting an MCE will often panic the guest kernel. After reset, however,
a new MCE will not be recognized because kvm thinks the first one is still
being processed.
Fix by exposing the MCE MSRs to userspace, which will clear them on reset.
Avi Kivity (2):
KVM: Expose MCE control MSRs to userspace
KVM: Document MCE banks non-exposure via KVM_GET_MSR_INDEX_LIST
