I don't really think you can, at least not directly. The problem is that
the X server typically wants direct access to the video hardware, and the
domU guest isn't allowed near it. Short of making your dom0 serial-console
only, I don't think you could do it.
I vaguely recall something about a framebuffer device appearing in Xen 3,
which you could point the X session in your domU at, but I could be
completely off-the-mark.
A way (not the only one, though) to get full X sessions happening is to
install an appropriate X server in your dom0, configure the domU to expose
it's display manager via XDMCP over the network (you can restrict who can
connect, for security), and then run something like
X -query <domU IP address>
in the dom0. Make it an init script if you want. That should start the X
server in the dom0, and then connect it to the display manager on the domU,
which should produce a nice GUI login screen.
Note that things probably won't run as well as they would normally, and 3D
accelerated graphics almost certainly won't work.
