startx is indeed the wrong thing. you may also have varied success if
you're trying to use xhost and the server is using xauth to lock
access to the display, although I'm not sure of the latter point. Try:

Container-Box: > xhost +
access control disabled, clients can connect from any host
Container-Box: > echo $DISPLAY
192.168.whatever:0

UML-Box: > export DISPLAY=192.168.whatever:0
UML-Box: > xterm

Now, if that doesn't work, you may have to start playing with xauth,
and it's been a while since I've had to touch it, but I think,
approximately, what you want is:

Container-Box: > xauth list $DISPLAY
192.168.whatever:0  MIT-MAGIC-COOKIE-1 4c4141730857551031247a133525251a

UML-Box: > xauth add [the entire line above]
UML-Box: > export DISPLAY=192.168.whatever:0
UML-Box: > xterm

And see if that gets you any further.

Cheers,
Waider.
