I think this apply to domU and dom0. 

I saw this  in source of vanilla  3.0/3.1rc2, and I saw this behaivor
in 2.6.34-xen (suse kernel), and even it 2.6.18-xen (rhel5.5 kernel).

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob_plain;f=arch/x86/xen/enlighten.c;hb=HEAD


static void xen_crash_shutdown(struct pt_regs *regs)
{
        xen_reboot(SHUTDOWN_crash);
}

static int
xen_panic_event(struct notifier_block *this, unsigned long event, void
*ptr)
{
        xen_reboot(SHUTDOWN_crash);
        return NOTIFY_DONE;
}
