Hi,

I'm trying to help progress a kernel regression hitting Fedora
infrastructure in which dozens of VMs run concurrently to execute QA
testing. The problem doesn't happen immediately, but all the VM's get
stuck and then any new process also gets stuck, so extracting
information from the system has been difficult and there's not a lot
to go on, but this is what I've got so far.

Does qemu there have this fix?

https://github.com/qemu/qemu/commit/cc071629539dc1f303175a7e2d4ab854c0a8b20f

I don't think so. The problem appeared in Fedora 34 which had
qemu-5.2.0 and now Fedora 35 which has qemu-6.1.0. I'll see about
backporting that patch if it hasn't already been in 6.1.0-13.fc35
