Hi
This is the migration PULL request.
Maybe it would better to use "PULL" instead of "PATCH" in the subject?
Now a not on CI, thas has been really bad. After too many problems
with last PULLS, I decided to learn to use qemu CI. On one hand, it
is not so difficult, even I can use it O:-)
On the other hand, the amount of problems that I got is inmense. Some
of them dissapear when I rerun the checks, but I never know if it is
my PULL request, the CI system or the tests themselves.
I normally peek at https://gitlab.com/qemu-project/qemu/-/pipelines to see
whether the problem occurred in one of the last staging CI runs already ...
or I push the master branch to my own repo to see whether it reproduces with
a clean state. That often helps in judging whether it's a new problem or a
pre-existing one.
This (last) patch is not part of the PULL request, but I have found
that it _always_ makes gcov fail. I had to use bisect to find where
the problem was.

I could use help to know how a change in test/qtest/migration-test.c
can break block layer tests, I am all ears.
Yes, I tried several times. It always fails on that patch. The
passes with flying colors.
Can you reproduce it locally by running "make check-block"?
The tests/qemu-iotests/tests/copy-before-write test seems to be doing some
things with snapshots ... maybe that's related?
