You can try adding "noreboot" to /boot/grub/menu.lst, it's a xen option, so 
you should put it after any other options in the kernel line corresponding to 
xen.

Then reboot and start your domU with "vcpus = 2", if it crashes dom0 won't 
reboot and you'll be able to connect a monitor and (probably) see the cause 
of the crash.
