True it is open source and should be possible. You're going to want to
make sure you use at least the 4.1 branch as it has better libxl
integration.

Continuation of this conversation, XCP is based on RedHat correct ? which version?

cat /etc/redhat-release

XCP release 1.0.0-42052c (xcp)

[root@xenserver-gvratnau ~]# uname -a

Linux xenserver-gvratnau 2.6.32.12-0.7.1.xs1.0.0.311.170586xen #1 SMP Tue Feb 1 17:10:20 EST 2011 i686 i686 i386 GNU/Linux

And if i use the source ISO im not getting version 4.1, so i need to natively build XEN 4.1 branch on some redhat release... then "remaster" the iso so its installable

on multiple systems without the pain of manually doing this to say 20 machines. I realize im way ahead of the curve here probably and am willing to suffer through

some pain, and well report back, document the needed steps, however the remastering piece im sure someone can provide a clue to how this is done.
