Hm... I did run 'make check-block' on a FreeBSD VM before sending the
pull request, but it turns out I ran it on the wrong branch. *sigh*

After rerunning it with the right one (and manually so that I get all
tests, not just those in 'make check-block'), however, while I'm seeing
some failures, my list of failing cases and your list are completely
disjoint:

    Failures: 115 125 145 182 286 298 300 migrate-bitmaps-postcopy-test
    migrate-bitmaps-test

All of these are test cases that are not run during 'make check-block',
so I would assume that they were already broken before.

So there seems to be something more specific to the environment that
made your test cases fail than just FreeBSD.

This is not good, and it can easily be reproduced on Linux by simply
changing the reference output of a test so that it fails. 'check'
doesn't seem to return the right exit code any more.

These seem to be intermittent -- a rerun was fine. (I have a theory
that the test framework handles "QEMU process died due to the VM
running out of memory" and similar kinds of error very badly:
I semi-regularly find that when the OpenBSD, FreeBSD and NetBSD
VM jobs are running in parallel on the same machine that one
might fail but succeed on a rerun.)

Applied, thanks.

Please update the changelog at https://wiki.qemu.org/ChangeLog/6.0

That's bad. I'll make a patch.

Intermittent, but not very intermittent -- I've just run about
three lots of the NetBSD vm test run in a row trying to get a
pass through, but something in iotests dies every time :-(

It seems to consistently be these five. What do they have
in common ?

That's a very good question, especially if you ask what they have in
common with each other, but with no other test.

With 030 040 041, your theory of running out of memory seemed to make a
lot of sense because these are the big block job tests. But 127 doesn't
fit in that group at all, it's a very small test on a tiny 64k image.
Unlike the other tests in your list that make use of our Python
framework, it's also just a shell script.

Other criteria that make 127 special like that it uses scsi and/or
iothreads don't apply to all other failed cases, but instead to other
cases that pass.

Are you still getting the same error message and is it the same for all
Python test cases? ("Unexpected empty reply from server") If QEMU had
been killed, there should be a message telling with which signal it
exited (if that code works correctly on NetBSD).

In any case, the output for 127 must be different because it doesn't use
the Python framework. Can you post the diff for that one?

I reproduced once (didn't save any logs). Now I patched check-block:

--- a/tests/check-block.sh
+++ b/tests/check-block.sh
@@ -77,7 +77,7 @@ export PYTHONUTF8=1
  
  ret=0
  for fmt in $format_list ; do
-    ${PYTHON} ./check -makecheck -$fmt $group || ret=1
+    ${PYTHON} ./check -d -$fmt 30 || ret=1
  done

to see some information when it fails and try to reproduce again.

Hmm.

I've run

   make -j9 vm-build-netbsd J=9

two hours ago, and it's still running.

it's now at position

Why is it so slow? Any options to make it faster?
