[Qemu-devel] [PATCH v2 0/5] iotests: Make some tests less flaky

[Max Reitz <mreitz@redhat.com>]

There are a couple of tests that fail (on my machine) from time to
time (and by that I mean that recently I've rarely ever had a test run
with both 083 and 136 working on first try).
This series should fix most (at least the issues I am aware of).

Notes:
- 083 might have another issue, but if so it occurs extremely rarely and
  so I was unable to debug it.

- 129 is flaky, too, because it tries to use block jobs with BB
  throttling -- however, block jobs ignore that these days.  Making it
  use a throttle filter node will require quite a bit of work.  See
  http://lists.nongnu.org/archive/html/qemu-block/2017-11/msg00111.html
  for more.

- 194 sometimes hangs because the source VM fails to drain its drive.
  This is probably not an issue with the test, but actually an issue in
  qemu.  See
  http://lists.nongnu.org/archive/html/qemu-block/2017-11/msg00256.html
  for more.
