Public bug reported: We are using kvm virtualization on our servers, We use "qemu-monitor-command"(drive-backup) to take qcow2 backups and to monitor them we use "qemu-monitor-event" command For eg:- /usr/bin/virsh qemu-monitor-event VPSNAME --event "BLOCK_JOB_COMPLETED\|BLOCK_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. Can you suggest how can we debug this further to find the actual issue. /usr/bin/virsh version Compiled against library: libvirt 4.5.0 Using library: libvirt 4.5.0 Using API: QEMU 4.5.0 Running hypervisor: QEMU 2.0.0 cat /etc/os-release NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/"; BUG_REPORT_URL="https://bugs.centos.org/"; CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7" ** Affects: qemu Importance: Undecided Status: New -- 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 stukcs randomly Status in QEMU: New Bug description: We are using kvm virtualization on our servers, We use "qemu-monitor-command"(drive-backup) to take qcow2 backups and to monitor them we use "qemu-monitor-event" command For eg:- /usr/bin/virsh qemu-monitor-event VPSNAME --event "BLOCK_JOB_COMPLETED\|BLOCK_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.
