Hi, thanks for your help.
I'm trying to have qxl full working on xen since end of 2011.
Since half of 2012 is at least working as standard vga.
The libxl patch should be correct, also with memory size setting.
I have tried same parameters of libxl qxl patch without xen and are working.
Also without kvm was working even if performance was really bad but at 
least qemu did not crash on start with qxl driver.
Based on this test the problem seems to be xen related problem, probably 
about hvmloader.
I have tried a lot of time to found exactly what the problem is without 
success for now.
I have very little knowledge about these parts.
Spice basic functions already present on libxl are working and also 
vdagent and usbredirection (vdagent patch already posted and 
usbredirection patch need improvements but already working).
If you will find the problem you are very welcome and I'll be happy to 
hear from you.
