Doesn't freenx use X? I haven't installed but will try it.
What I did try was to leave X off on workstation and built a fedora guest. I
also connected to the workstation from another machine via ssh and I tried
running the virt-viewer via X-forwarding, it stayed up for about 10 or 15
minutes and crashed. Since I could see the console on the work station then,
it showed a kernel panic.
After rebooting I opened a terminal via ssh and it seems ok -- up for about
30 minutes so far, I'll check in the morning.
The trouble with that is I usually connect to the workshop via vnc, so I'm
not sure the guest will be of much use.
