Subject: | [Qemu-devel] [PATCH 0/2] HyperV equivalent of pvpanic driver |
Date: | Thu, 11 Jun 2015 16:18:34 +0300 |
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.
