Your options are:
1) run "vncserver" in the guest
2) SSH to the guest and use X11 forwarding to get graphical access, just as 
you would for a separate machine
3) Run the FreeNX server in the guest and connect using the NoMachine NX 
client from outside

I imagine that failed due to Xen's PCI interface forbidding SVGAlib from doing 
something - has anyone actually tried SVGAlib under Xen?

Easiest would be to install X11 in dom0, then use one of the network-based 
solutions I mentioned in order to get access to the other domains.
HTH,
Mark
PS. Thanks for the picture!
