Based on UTAH code and on the assumptions made due to the debugging I created a test script that tries to trigger the cleanup being concurrent to the undefine calls.
I aran 600 loops - so far nothing triggered, so we miss some aspect of the original issue. Maybe the reason/way qemu dies is different? Maybe we need a case where libvirt writes to qemu on some of those streams? Not sure yet, for now I enable a debugging log of libvirt on s1lp4 to maybe get better insight this happens next time. @paride - please ping me when it happens next time so we can check the logs @paride - if anything comes to your mind how this guest abort could be different let me know ** Attachment added: "test script (not triggering it yet)" https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1822096/+attachment/5250194/+files/test.py -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822096 Title: libvirt hangs after utah workload is aborted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1822096/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
