Subject: [PATCH 2/3] KVM: x86: properly restore LVT0
Date: Tue, 30 Jun 2015 22:19:17 +0200 [thread overview]
Message-ID: <1435695558-3168-3-git-send-email-rkrcmar@redhat.com> (raw)
In-Reply-To: <1435695558-3168-1-git-send-email-rkrcmar@redhat.com>
Legacy NMI watchdog didn't work after migration/resume, because
vapics_in_nmi_mode was left at 0.
