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

Subject: [Qemu-devel] [PATCH 0/5] iotests: Make some tests less flaky
Date: Thu, 9 Nov 2017 02:37:59 +0100

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).

- 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
  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
  for more.

"All tests have passed, let's ship it!"
-- Me, 2:36 am

(Editor's note: "all" means raw/file, qcow2/file, and raw/nbd.)

Max Reitz (5):
  iotests: Make 030 less flaky
  iotests: Add missing 'blkdebug::' in 040
  iotests: Make 055 less flaky
  iotests: Make 083 less flaky
  iotests: Make 136 less flaky
