For this we need to know which bugs are still valid and which could be closed already. Thus we are setting the bug state to "Incomplete" now. If the bug has already been fixed in the latest upstream version of QEMU, then please close this ticket as "Fix released". If it is not fixed yet and you think that this bug report here is still valid, then you have two options: 1) If you already have an account on gitlab.com, please open a new ticket for this problem in our new tracker here: https://gitlab.com/qemu-project/qemu/-/issues and then close this ticket here on Launchpad (or let it expire auto- matically after 60 days). Please mention the URL of this bug ticket on Launchpad in the new ticket on GitLab. 2) If you don't have an account on gitlab.com and don't intend to get one, but still would like to keep this ticket opened, then please switch the state back to "New" or "Confirmed" within the next 60 days (other- wise it will get closed as "Expired"). We will then eventually migrate the ticket automatically to the new system (but you won't be the reporter of the bug in the new system and thus you won't get notified on changes anymore). Thank you and sorry for the inconvenience. ** Summary changed: - qemu-monitor-event command stukcs randomly + qemu-monitor-event command gets stuck randomly ** Changed in: qemu Status: New =3D> Incomplete -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1926596 Title: qemu-monitor-event command gets stuck randomly Status in QEMU: Incomplete Bug description: We are using kvm virtualization on our servers, We use "qemu-monitor-comm= and"(drive-backup) to take qcow2 backups and to monitor them we use "qemu-m= onitor-event" command = For eg:- /usr/bin/virsh qemu-monitor-event VPSNAME --event "BLOCK_JOB_COMPLETED\|B= LOCK_JOB_ERROR" --regex the above command stucks randomly (backup completes but still it is waiting) and because of which other vms backup are stucked until we kill that process.
