      Sorry, same result as what?  Does the X driver work or not?

    X qxl driver works with sse disabled (tried also with the correct sse4.1

It's good to hear QXL actually works with Xen qemu-upstream,
(in the future) when the SSE issue is fixed!

How about Anthony's patch for QXL.. Is that OK for for Xen 4.3,
or should that wait for 4.4 ?

Unless qxl is useable with sse2 disabled, there's no benefit to having the QXL fix in 4.3. The only reason Anthony might do it is to be able to take it off his queue of things to do later -- I would leave it to his discretion.
