My bad. After adding 'noreboot' I could see that it couldn't mount the
initrd... I'd forgotten to add 'CRAMFS' in my config so the kernel
panicked. The annoying thing was that it hung on reboot.

Has xen changed the way it does a reboot between 2.0.6 and 3.0? This
machine has been able to do a reboot in the past.

I've been bitten by this sort of error before (ie a kernel panic caused
by something I've done wrong but I've missed it because xen rebooted),
could we add in a delay (5 seconds would do, or maybe a boot option)
before xen reboots?

Thanks

James

If you add "noreboot" you need to power-cycle by hand.

The problem I was having that xen appeared to have crashed and locked up
the machine. What was actually happening was that xen was doing a reboot
but caused a hang instead. By adding in noreboot, I could see that xen
was just trying to reboot and not actually crashing.
 
So if I take noreboot out, the machine hangs when xen tries to reboot.
Xen used to be able to do a reboot though, hence my question.
 
Sorry for the confusion.
 
James

Has xen changed the way it does a reboot between 2.0.6 and 3.0? This
