Sorry, I found that was introduced by new winpv drivers update instead 
and I solved applying this patch:
x86/hvm: Add per-vcpu evtchn upcalls v3 
http://lists.xen.org/archives/html/xen-devel/2014-11/msg00752.html
About save/restore problem with qxl I still not found a solution or at 
least the exact cause :(
