I've thought about this issue before, not sure how to fully solve it
though. If we set the display in the xml at install time (say setting
it to :0.0), but at a later time we ssh =Y into that machine, the 
display in the xml will be wrong, and possibly pop the sdl window on
someone else's display. Possibly a solution at the virsh or 
virt-manager level?
