XCP is based on xen 3.4 while libxenlight is developed and tested on
xen-unstable so I doubt that in the current state it would work.
However when XCP rebases on xen 3.5 it will inherit libxenlight
automatically.
In any case backporting libxenlight to xen 3.4 shouldn't be difficult
at all.

The xenstore implementation doesn't make any difference, the hypervisor
changes shouldn't create any problem, but few patches in the qemu
patchqueue might.
