Add "noreboot" to the boot.cfg line for Xen (or at the end of the Xen line
in menu.lst with GRUB):

menu=Boot Xen-HVM:load /netbsd_XEN3_DOM0 console=pc;multiboot /xen.gz
dom0_mem=<foo> noreboot

In case of crash, you have a chance of seeing it, instead of a hard

In the event that it does not work, there is a good chance that the
hardware is failing somewhere -- you really need a nasty dom0 (driver bug,
or compromised host) for it to successfully "powercycle" the hypervisor
without it knowing.
