Heartbeat is not a kernel level implementation.  The watchdog timer code is
part of the kernel (a module), but is purely optional and just resets the
machine if it can't get a heartbeat from itself.  But heartbeat works on its
own.

I would debate idea of creating a HA cluster out of Qube2s, but that is
another thread.
