Attach to the json event system. Load a guest such as Ubuntu 14.04 and run the 'halt' command. Guest ceases to execute, qemu freezes CPUs however no SHUTDOWN event is fired to the monitor. Now load a guest such as finnix or Debian 7. Run the same sequence of steps and note that the SHUTDOWN event is fired to the monitor. This seems like a qemu bug as the execution of the guest has ceased. Thanks Michael
