[Qemu-devel] [Bug 1217339] Re: SIGQUIT to send ACPI-shutdown to Guest

[Thomas Huth]

Please do not add patches to the bugtracker. Post them to the mailing
list instead. See http://wiki.qemu-project.org/Contribute/SubmitAPatch
for information how to contribute a patch.

(and I am also not sure whether SIGHUP is the right signal for this job
- the original request was also about SIGQUIT instead)

Title:
  SIGQUIT to send ACPI-shutdown to Guest

Status in QEMU:
  New

Bug description:
  When qemu receives SIGQUIT, it should first try to run
  system_powerdown (giving the guest an ACPI signal to begin the
  shutdown process), before ending the whole qemu process.

  At this point there is no way to do a graceful shutdown if you do not
  have access to the monitor and you do not use any wrapper like
  libvirt.

  If, for some reason SIGQUIT would not be accepted as the signal, take
  any free to use signal, like SIGUSR1. There should be a way to get
  ACPI shutdown sent to the guest.
