I would setup a network link between the "real" host and the uml host,
for example  with an ethertap interface  on the "real"  host, and then
use xhost on the "real" host to accept X connections from the uml host
and set the DISPLAY environment variable on the uml host.


Something like:


# ------------------------------------------------------------
# Configuring ethertap links.
# ------------------------------------------------------------
### Please run the following command as root:
insmod ethertap
### Please run the following command as root:
ifconfig tap0 arp mtu 1484  \
         10.116.117.1  \
         netmask 255.255.255.0  \
         broadcast 10.116.117.255  up 


# ------------------------------------------------------------ 
# Launching the User-Mode-Linux  virtual host connectiva-6.5
# root_fs_conectiva_20010420              24M RAM         32M SWAP 
#  eth0[10.116.117.2   /24]--> tap0[10.116.117.1   ]
#------------------------------------------------------------
umask 077
dd if=/dev/zero of=swap-connectiva-6.5-46-14966 bs=1M count=32
mkswap swap-connectiva-6.5-46-14966
xterm -title connectiva-6.5 -ls -sb -sl 2500 -fg '#004' -bg PaleGoldenrod \
      -e linux  eth0=ethertap,tap0  \
                mem=24M  \
                ubd1=swap-connectiva-6.5-46-14966  \
                ubd0=root_fs_conectiva_20010420  &

# ------------------------------------------------------------
# Configuring routes on the host.
# ------------------------------------------------------------
### Please run the following command as root:
route add -net 10.117.0.0/24  gw 10.116.117.2  dev tap0 

xhost +10.116.117.2


And on the uml host:

  ifconfig eth0 10.116.117.2 netmask 255.255.255.0 broadcast 10.116.117.255 up

  export DISPLAY 10.116.117.1:0.0
  xterm &
