[Qemu-devel] [PATCH v1 0/6] KVM: Hyper-V SynIC timers migration fixes

From: Andrey Smetanin
Subject: [Qemu-devel] [PATCH v1 0/6] KVM: Hyper-V SynIC timers migration fixes
Date: Wed, 23 Dec 2015 14:28:35 +0300

During testing of Windows 2012R2 guest migration with
Hyper-V SynIC timers enabled we found several bugs
which lead to restoring guest in a hung state.

This patch series provides several fixes to make the
migration of guest with Hyper-V SynIC timers enabled

The series applies on top of
'kvm/x86: Remove Hyper-V SynIC timer stopping'
previously sent.
