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.]

Rich.
