The easiest thing to do is to start the Xvnc server and then
connect in using vnc over the virtual network.

Alternatively, you could log in via ssh (with X forwarding) and
start an Xnest server.

In domain 0 you should be able to do an 'ifconfig' and see a
'vif1.0' virtual network backend interface.

Check that the bridge stuff is setup OK by doing a 'brctl show xen-br0'

Next, bring up the console of the other domain e.g. 'xm console
domain1' login, and use ifconfig to check you've got the IP address and
routing setup OK.

As Ian says, the best solution is to choose your favourite network display
protocol and run the server for that. The screenshots on the Xen homepage
were prepared by configuring the unpriv domains to run VNC X server and then
connecting using the KDE VNC client running in domain 0. You can also use
straight X forwarding, like you would to connect to another *nix box.

You might also want to check out FreeNX and / or commercial NoMachine X
(FreeNX is currently still in an early state of development) since this also
handles printing and sound elegantly and has excellent performance.

There is one brave soul trying to get a virtual machine to directly control
his second graphics card, which will be pretty cool once it's working (i.e.
have two monitors and keyboards attached to the same machine, controlled by
different VMs).

HTH,
Mark
