File aeda1b8c-qemu-no-error-shutdown.patch of Package libvirt.9596

commit aeda1b8c56dc58b0a413acc61bbea938b40499e1

    qemu: monitor: do not report error on shutdown
    
    If a shutdown is expected because it was triggered via libvirt we can
    also expect the monitor to close. In those cases do not report an
    internal error like:
      "internal error: End of file from qemu monitor"
