> A Watchdog timer can be used by the hypervisor to verify if an Instance is
> still alive. If not, for example due to a kernel panic the HV can reset the
> Instance so that it boots again.
> Inside the Instance the 'watchdog' daemon has to run to provide this. If the
> Watchdog is not running the HV can't verify if the Instance has crashed.
> This is supported by Libvirt and Qemu and can be configured in the XML:
> https://libvirt.org/formatdomain.html#elementsWatchdog
