I think that porting spice and qxl to the current qemu-xen tree is not
worth the effort, considering that we are very close to having xen
support in upstream qemu right now.
  Good news. How long will it be released?

Also if you don't want to wait for xen support to go upstream in qemu
you can checkout Anthony Perard's git qemu branch and work directly on

git://xenbits.xen.org/people/aperard/qemu-dm.git qemu-dm-v12
