Title:
Recent KVM RTC cherry-picks break (some) Windows Live-Migrations
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Xenial:
Fix Released
Bug description:
== SRU Justification ==
Impact: Windows Live-Migration does not work reliably anymore with
recent KVM RTC cherry-picks.
Fix: Single follow-up upstream cherry pick which fixes the problem.
Regression Potential: The patch has been upstream since 4.8, so it
should be well-tested at this point. Thus regressions are unlikely.
---
The fix for
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1649718 cherry-
picked three commits from upstream 4.6 related to RTC interrupt
handling. Unfortunately, the followup commit included in 4.8 was
missed. As a result, Windwos Live-Migration in Qemu is broken on
certain hardware.

Live-Migrating a Windows Server 2016 VM (Qemu commandline below) hangs
the VM in about 1/3 attempts. Interestingly, migrating the VM back to
the original host allows the VM to run normally again (but subsequent
migration attempts might hang it again as well).

The causing commits were triaged via git bisect, applying the follow-
up commit b0eaf4506f5f95d15d6731d72c0ddf4a2179eefa fixes the issue
with no observable side-effects. Mainline 4.6 is also affected and
triggers the bug just like Ubuntu kernels >= Ubuntu-4.4.0-63.84
