Subject: [Qemu-devel] [PATCH 0/2] HyperV equivalent of pvpanic driver
Date: Thu, 11 Jun 2015 16:18:34 +0300 [thread overview]
Message-ID: <1434028716-6767-1-git-send-email-den@openvz.org> (raw)
Windows 2012 guests can notify hypervisor about occurred guest crash
(Windows bugcheck(BSOD)) by writing specific Hyper-V msrs. This patch does
handling of this MSR's by KVM and sending notification to user space that
allows to gather Windows guest crash dump by QEMU/LIBVIRT.
The idea is to provide functionality equal to pvpanic device without
QEMU guest agent for Windows.
The idea is borrowed from Linux HyperV bus driver and validated against
Windows 2k12.
