I regularly before a release pull in fixes that were posted for qemu-stable.
This is one of them, I'll again do such a build and retest this issue with it.
I identified and backported (only one needed modification) 33 patches.
But as usual there might be some context needed on top - I have build
Hi Christian,
Yes,
seems that the patch you mentioned fixing the issue i rebuilt the qemu with the
patch and it's work fine now.
Thank you guys.

That commit you mention is confirmed to solve a bug reported against
Fedora with almost the same stack trace you see here.

At the breaking function we have:
29 void notifier_remove(Notifier *notifier)
30 {
31 QLIST_REMOVE(notifier, node);
32 }
(gdb) p notifier
$1 = (Notifier *) 0x55d2f40c5078
(gdb) p *notifier
$2 = {notify = 0x0, node = {le_next = 0x0, le_prev = 0x0}}
And since QLIST_REMOVE
Hi Christian,
yes that exactly what we see in our tests,
so are the logs that you asked for in comment#1 still needed?
also if you fix it can you please provide us a link for a package or even a
workaround until the issue resolved, since this issue stuck our QA from testing
ASAP over Focal.

I changed the bug task to Qemu (Ubuntu) as this isn't a libvirt error.
I also added an upstream qemu task in case this is a known issue for the
developers there. Someone might be able to point us at a known
discussion/fix.
The Backtrace I added in the last comment should help to identify known
16 matches
