Title:
  qemu-monitor-event command gets stuck randomly

Status in QEMU:
  Expired

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.

  Can you suggest how can we debug this further to find the actual
  issue.

  
  /usr/bin/virsh version
