            <tr>
              <td>

          </table>
          <blockquote head="Displaying X clients on the host X server">
First of all, make sure that you have the X clients installed in the
filesystem that you're going to boot.  Then boot the virtual machine
and set up networking to the host.  See the 
<a href="networking.html">networking tutorial</a> for instructions on
doing that.  If necessary, xhost the virtual machine on the host.
<p>
At this point, set your display to the host 
<blockquote>
              <tt>
                <font color="#000000">export DISPLAY=host-ip:0</font>
              </tt>
            </blockquote>
and run whatever X clients you want.
</blockquote>

<a name="Running a local virtual X server"/><table width="100%" bgcolor="#e0e0e0">
            <tr>
              <td>
                <b>
                  <font color="black">Running a local virtual X server</font>
                </b>
              </td>
            </tr>
          </table>
          <blockquote head="Running a local virtual X server">
Before booting the virtual machine, make sure that it contains Xnest,
which is the UML X server.  On some distributions, it is packaged with
the X clients, and on others, it's not.  Then boot the virtual
machine, and follow the directions above to run Xnest displaying on
the host.  Xnest will create a window which will be its root window.
All clients of the Xnest will be displayed within that window.
<p>
Now, set your display to the default local X server:
<blockquote>
              <tt>
                <font color="#000000">export DISPLAY=:0</font>
              </tt>
            </blockquote>
and run whatever X clients you like.  I normally run fvwm2, which
gives me enough of an X environment that I don't need to go back to
the console.
<p>
See the <a href="net.html">virtual network</a> and <a href="x.html">X 
session</a> screenshots for examples of X in action under UML.
