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.
