I was hoping that there is something like when one runs ./tests/qtest/migration-test I thought I saw some patch today that to save more artifacts. But the bottom line is that we don't emit enough stuff from any of our tests to debug them from logs -- we're too used to using other methods. And I don't understand what CFI is (and I don't rule out that posibility) or I can't understand how checking indirect functions call can make migration-test die without a single CFI error message? CFI (control flow inspection/validation/somesuch) adds checking along call paths, which may affect timing. This is almost certainly some sort of race condition. Do we have a way to run on that image: ./tests/qtest/migration-test in a loop until it fails, and at least see what test is failing? Not as is, no. You'd have to create a new CI job, and for that you'll need advice beyond myself. r~

I can't see a single function that is new/change prototypes/etc that is changed on this series. So is this problem related to CFI? Or it is a migration problem that somehow only happens when one use CFI? Inquiring minds what to know. Any clue?

RE: [PULL 00/30] Next patches
Hi, All,
Very appreciated for your time on reviewing our patch.
The second CI failure caused by our patch has been addressed. One simple
way is moving "#endif" in qemu/tests/bench/xbzrle-bench.c from line 46 to line
450.
We have submitted patch v7 to update this modification. Thanks for your time
again.
Best Regards,
Ling

Re: [PULL 00/30] Next patches
Please only include bug fixes for 7.2 in pull requests during QEMU hard freeze. The AVX2 support has issues (see my other email) and anything else that isn't a bug fix should be dropped too. Stefan

I think the issue is that the test links against objects that aren't
present when qemu-user only build is performed. That's my first guess,
I might be wrong but it is definitely this commit that causes the
failure (I bisected it).

Re: [PULL 00/30] Next patches
Please don't merge this PULL request,
It contains changes to the "io" subsystem in patch 3 that I
have not reviewed nor acked yet, and which should be been
split as a separate patch from the migration changes too.
With regards,
Daniel
