BTW this is not true. The two watchdog devices are supported
by all Linux guests.
Windows guests do not support them, but Windows lacks[1] any sort of
watchdog framework so lack of device support is the least of your
problems. There would be nothing for the device to plug into (unlike
the /dev/watchdog API on Linux), nor is there any daemon to support it
(unlike the 15 year old watchdog daemon on Linux).
Rich.
[1] Yes, this exists:

but it requires a special version of Windows.
