Ok, so after I've been struggling with a failing msys2-32bit job for my new 
upcoming pull request the last two days (I thought I had a bad patch in 
there), where I had some problems with the test-hmp and qom-test qtests, 
I've come up with a new theory after looking at this CI run from the 
qemu-project staging branch and seeing that these tests are also failing there:

 https://gitlab.com/qemu-project/qemu/-/jobs/3558798544
 https://gitlab.com/qemu-project/qemu/-/jobs/3560870904

That might also explain the timed-out job that you have seen earlier, Peter, 
it was likely a hanging qom-test since that seems to be the first test to be 
executed during the "make check" there.

So the qtests for Windows are definitely not ready for the CI yet (after 
we've enabled them just in December). I think it's best to disable them 
there again completely until the issues are understood and fixed.
