Bug Description

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The v4.2.8-ckt3 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://kernel.ubuntu.com/ubuntu/linux.git

    TEST CASE: TBD

       The following patches from the v4.2.8-ckt3 stable release shall be applied:

Hi,

commit 3f11933efc9ef55ecb2ac7e6d626e8d05a99a4b1 - KVM: x86: expose MSR_TSC_AUX to userspace
breaks KVM/QEMU live migration of host with a graphical user interface.

== Software Versions: ==
Kenel: this one, namely: Ubuntu-4.2.0-30.35
kvm-qemu: 2.5.0

== Reproduction ==
Install kernel with 3f11933efc9ef55ecb2ac7e6d626e8d05a99a4b1 included (Ubuntu-4.2.0-30.35)
Start VM with GUI
Start migration (no post copy, same migration as you'd in qemu 2.4)
When migration has finished snf you switch the vnc over to the migration target the VM running but frozen showing the last frame buffer, its also not ping-able

== VMs tested ==
Linux Mint Live ISO
elementaryOS Live ISO
Windows 7

VMs tested with minimal configuration. No disks on live cds, no network (but also with both enabled tested, same result)

== Hardware Used ==
Two Nested VMs on an Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz
Two physical supermicro servers with Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz
NFS for storage (for the live ISOs and diskes)

==
If I revert 3f11933efc9ef55ecb2ac7e6d626e8d05a99a4b1 and install the kernel on _both_ hosts the freeze does not happen anymore.
But this commit is also included in the ubuntu-xenial kernel (master and master-next tested) and there I have no such problem, thus its a side effect from some other (missing?) commit.

I'm currently trying to break the problem further down and try find the real culprit (or get closer to it).

Backtrace of the hung Linux Mint ISO follows in next comment.

Follow up, I tried it with a Ubuntu Server and Alpine Linux without any gui and it frozed also, same backtrace.

Sorry I could swear Alpine Linux did not froze when I first tested it in a nested VM.

Thomas Lamprecht (t-lamprecht) wrote :

Soo, after some digging I found the root cause, while those two KVM patches listed above were backported/added another on was not, namely:
81b1b9ca6d5ca5f3ce91c0095402def657cf5db3
KVM: VMX: Fix host initiated access to guest MSR_TSC_AUX

I backported it to this Ubuntu-4.2.0-30.35 kernel and tested it successfully.
