I agree. The thing of interest is whether the guest is running, not
whether QEMU is running.
It would be good for the internal watchdog device to have the option
of no effect except for its status to be available in the QEMU
monitor, so management apps can see when the guest has crashed.
Steve's idea of a matrix (Guest event -> QEMU action) is a good one,
and could include "watchdog not pinged" as a guest event.
