You need to have CONFIG_XEN_FRAMEBUFFER support in the domU kernel and
create a virtual framebuffer device in the domU config vfb = [
'type=vnc,vncunused=1' ] (see the example configuration files for other
parameters).  X then needs to use the fbdev driver.  In this example you
would connect to the graphical interface with a VNC client.
