Agreed. The qemu watchdog lets you do this already. You can (using
the qemu monitor, or libvirt) capture watchdog events and put them
into your management application. Watchdog firing does *not*
necessarily mean a guest reboot.
[Note what I say applies to the qemu watchdog device. The Linux
watchdog daemon may independently initiate a guest reboot, but you can
configure it to perform other actions instead.]
