I don't think this is UML specific - I think your X configuration is the
problem. You should get your X configs correct using two physical hosts first,
then the list can help with UML-specific problems.
As a suggestion, you would probably do better to use X forwarding through ssh
rather than using xhost and manual DISPLAY settings. This way you only need to
allow the ssh port connection between the two hosts. X forwarding usually works
straight out of the box (ssh -X from the host where the window is to be
displayed). Using xhost+DISPLAY is much more error prone and less secure.
If you really want to use xhost+DISPLAY I would suggest you start with a simple
TCP (eg. telnet) example to get networking sorted before moving onto the
complexity of X.
