These can be grouped into a single option of the form: -action event=action Which can be used to specify the existing options above in the following format: -action reboot=none|shutdown -action shutdown=poweroff|pause -action watchdog=reset|shutdown|poweroff|pause|debug|none|inject-nmi This is done in preparation for adding yet another option of this type, which modifies the QEMU behavior when a guest panic occurs.
