  • Thread-topic: xen and reboots

I know I've asked vaguely the same questions before, but when dom0
reboots, is it dom0 or xen that actually reboots the machine?

What about when, say, softdog (the software watchdog kernel module) does
a reboot?

I ask because if I say 'reboot', one system I have just hangs, with the
monitor in 'standby' mode (eg no signal), whereas if I kill the watchdog
daemon (with softdog loaded with nowayout=1), it reboots fine, but
obviously doesn't do a clean shutdown.

Is there a way to change the style of reboot that xen uses? Or should I
be looking at asking dom0 to reboot differently?

Thanks

James
