[Qemu-devel] [Bug 1089005] Re: Qemu does not shutdown with vnc enabled on OS X

[Peter Maydell]

Interesting -- my experience is that control-C doesn't work at all, even
if using the cocoa UI frontend. It's a bug of some kind related to
signal handling but I haven't been able to track it down. As far as I
could tell with a debugger QEMU never received the SIGTERM at all, which
makes no sense to me.

As a workaround you can send QEMU a SIGKILL, which will abruptly
terminate QEMU (NB that if you have a writable disk image you may find
it is corrupt since this is a long way from a clean shutdown). The best
approach would be to make the guest cleanly power down the VM, which
should cause QEMU to exit automatically.

Title:
  Qemu does not shutdown with vnc enabled on OS X

Status in QEMU:
  New

Bug description:
  I am running OS X 10.8.2 and Qemu 1.3.50 from your git repository.

  Running

      qemu-system-i386 <image>

  works fine. I can quit the process using ctrl-c.

  When I try to use

       qemu-system-i386 -vnc :<port> <image>

  ctrl-c does nothing and I have to kill the process trough the activity 
monitor.
  Furthermore terminating the process from my java program does not work 
either. 
  I have also posted a question on Stackoverflow:
