Yes i know the difference between XL and XM toolstacks and have been 
using Xen 4.2-unstable with XL since the beginning of my Xen journey. As 
i mentioned before, i never had this issue with a previous Xen 4.2 
person as i mentioned it, HOWEVER i have messed around with XCP and 
different version of Xen on this Debian before, SO very likely i forgot 
to remove or uninstall something between changes, just trying to figure 
out how to make it stop asking me to force anything.

I was checking to make sure XEND was stopped by running "*sudo 
/etc/init.d/xend stop*" and i get an error message as below:

*Traceback (most recent call last):
   file "usr/sbin/xen", line 36, in <module>
     from xen.xend.server import SrvDaemon
ImportError: No module named xen.xend.server*

WHICH also happens to be the exact same message i have been getting 
every time i shut down Dom0 for quite a while now and been meaning to 
ask about that.

Once i run "*sudo update-rc.d xend stop*" than i am able to run "*sudo 
xl create*" without the FORCE option, but once i reboot the system, it 
comes back and have to run the "*sudo update-rc.d xend stop*" all over 
again. SO wondering how to disable xend from loading at boot time? Or 
just get rid of whatever remnants floating around that is interfering 
with things.
