Many physical PCs have a hardware watchdog. This is a good way of getting up and running again if you somehow have a bug that causes a deadlock. If you run linux in DomU you will have to use a software watchdog. The kernel provides such a software watchdog. But could there be scenarios where the DomU domain will lockup without the software watchdog goes off? Interrupts? So my question does XEN provide a "hardware" watchdog that the user domains can use? It might be safer that the counter and trigger resides in the XEN domain than in the user domains. Regards, -- Andreas Bach Aaen System Developer, M. Sc.
