Bug#885166: instability with 4.14 regarding KVM virtualization



Package: src:linux
Version: 4.14.2-1
Severity: normal
Tags: upstream

Hi,

starting with kernel 4.14, the majority of mv KVM virtualization hosts
has become unstable. This behavior has been present in every 4.14
kernel, regardless of self-compiled or the Debian kernel. I am reporting
this in Debian in hope that I can get more input here than I got on the
linux-kernel mailing list.

The issue happens on various Debian stable hosts (didn't try unstable
yet) with AMD and Intel CPUs, including:

  - Model name:            AMD GX-412TC SOC
  - Model name:            Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz
  - Model name:            Quad-Core AMD Opteron(tm) Processor 1389
  - Model name:            Intel(R) Core(TM) i7 CPU 950  @ 3.07GHz

The symptoms appear more often when the system is under tight memory
conditions and/or KSM is enabled. Disabling KSM decreases the frequency
of the issue happening, but doesn't make it stop. Going back to a 4.13
kernel makes all machines rock-stable again. I also see this behavior in
4.15 release candidates kernels up to -rc4 (-rc5 test still pending).

Symptoms are (choose any combination).

  - VMs hanging completely: no ping, no reaction on serial console
  - VMs losing their storage: machine still pings, login not possible,
    no "password" prompt after entering user name on serial console
  - reliable and reproducible segfault of certain binaries in the VM
    until the VM is restarted
  - VM file systems being re-mounted r/o
  - VM file systems being corrupted so that external fsck is necessary
  - virsh shutdown not working for affected VM
  - sometimes, even virsh destroy not working (hanging for minutes until
    Ctrl-C, sometimes error message, unfortunately not written down)
  - host not rebooting cleanly, needing hardware reset

I tried bisecting the kernel between 4.13 and 4.14, but the results are
inconclusive to me:

- 569dbb88e80deb68974ef6fdd6a13edb9d686261 is good
- ddf720f86efe38cb3ef88b2eaad9ea8ad7c6f798 is bad
- ddf720f86efe38cb3ef88b2eaad9ea8ad7c6f798 was the result of the kernel
  bisect between 4.13 and 4.14, but is a one-character typo fix in a
  comment.
- I am also confused that ddf720f86efe38cb3ef88b2eaad9ea8ad7c6f798 is in
  4.13-rc7, therefore earlier than the "good" 4.13 relese

In the second try, I tried bisecting between those two commits. This
quickly results in:
The merge base cc4a41fe5541a73019a864883297bd5043aa6d98 is bad.
This means the bug has been fixed between
cc4a41fe5541a73019a864883297bd5043aa6d98 and
[569dbb88e80deb68974ef6fdd6a13edb9d686261].

569dbb88e80deb68974ef6fdd6a13edb9d686261 is Linux 4.13 and is good
cc4a41fe5541a73019a864883297bd5043aa6d98 is Linux 4.13-rc7 and is bad.

Bisecting between those ends up in:
[6/4993]mh@fan:~/linux/git/bisect/linux ((v4.13) *|BISECTING) $ git
bisect good
Some good revs are not ancestors of the bad rev.
git bisect cannot work properly in this case.
Maybe you mistook good and bad revs?
git [5/4992]mh@fan:~/linux/git/bisect/linux ((v4.13) *|BISECTING) $ git
bisect log
git bisect start
# bad: [cc4a41fe5541a73019a864883297bd5043aa6d98] Linux 4.13-rc7
git bisect bad cc4a41fe5541a73019a864883297bd5043aa6d98


What am I doing wrong here? Any idea what to do here?

Greetings
Marc
