Hello, could you please help me on trying this.
https://reviews.freebsd.org/D52049

I create a instance on Vultr and discover the same problem for FreeBSD
instance. Therefore, I spend an afternoon on reading the documentation and
implementing the driver.

For enable auto reboot when timeout, you should set hw.i6300esb.reboot=1 and
set the watch dog with WATCHDOG_ACTION_SHUTDOWN in qemu through qemu-monitor.
In guest, you can use watchdog -t <timeout_time>.
