I have attempted once to force install all of the xcp packages manually 
and one at a time. What i tried was while already having installed the 
latest Xen 4.2-unstable, booted into Non-Xen kernel, install all non XCP 
related packages and libraries thru normal means via synaptic, then 
downloaded manually each XCP package and installed it manually one at a 
time, sometimes using force install.  I know, most would allready know 
it wouldn't work, but i just  tried it once anyways for kicks, BUT i 
lack the understanding on how to properly configure each package so that 
it loads the right things and communicates with Debian and to each XCP 
package, so most things were never configured so the XE toolstack never 
did load, and the blk. It was just my feeble attempt.

From my understand what some have mentioned or told me is that the XAPI 
version, that is made for Debian type linux, has to be compiled and 
built to worth with a specific version of Xen. SO if currently the XAPI 
on Debian works with Xen 4.1.2, than it will not work with Xen 4.2 
unless it is again written and compiled to work wtih Xen 4.2, which as 
you stated is not released yet.
SOOO, just out of curiosity, any ideas of when you guys might release 
the version of XAPI that will run on Xen 4.2? Will it ONLY happen once 
Xen 4.2-unstable becomes Xen 4.2 Stable (suppose that would be logical 
sense)? Just wondering how long one might have to wait... :)
ALSO, would the version of XAPI that was lets say made to work with Xen 
4.2 be the equivalent to XenServer 6? OR would it be newer than 
XenServer 6, lets say 7 for example?? Just curious on how Xen 4.2 
equates to XenServer? AS i think, XCP 1.1 is pretty much the same thing 
as XenServer 5.6.x AND XCP 1.5 is the same thing as XenServer 6. SO than 
i guess, Xen 4.2 would be like XenServer 7? Anyways just guessing and 
curious on the how different versions are introduced.
