It should now be possible to restart the system and use Xen. Reboot and
choose the new Xen option when the Grub screen appears.
What follows should look much like a conventional Linux boot. The first
portion of the output comes from Xen itself, supplying low level
information about itself and the underlying hardware. The last portion
of the output comes from XenLinux.
You may see some error messages during the XenLinux boot. These are not
necessarily anything to worry about--they may result from kernel
configuration differences between your XenLinux kernel and the one you
usually use.
When the boot completes, you should be able to log into your system as
usual. If you are unable to log in, you should still be able to reboot
with your normal Linux kernel by selecting it at the GRUB prompt.
