Here there is a patch that add qxl support in libxl updated to xen 4.4-rc3
if you want add it:
https://github.com/Fantu/Xen/commit/f1e3f78f7b9580700591cebd98e9263645bff56b
Or you can simply compile from this already ready for spice/qxl testing:
https://github.com/Fantu/Xen/commits/rebase/m2r-testing

Is not upstream for now because there is something on xen that make it not
working on linux domUs with qxl driver active and working with high
performance problem on windows domUs.
I spent several days without finding the exact problem to be solved :(
If you want you can try it out and see if anything changes using Fedora instead
of Debian as dom0, differents kernel domUs etc.
Maybe you could even find some new informations/errors useful for solving the
problem.
