About libxl patch for QXL support is still the same except the refresh 
with new xen-unstable.
My latest test is based on this source that include all my latest patches:
https://github.com/Fantu/Xen/commits/rebase/m2r-next
I'll repost it with updated and full noted in description.
Regarging qxl problem on xen linux domUs I didn't found other useful 
details to solve the problem and I not have sufficient time now for 
advanced debug.

Thanks for any reply and sorry for my bad english.
