Saw that you tracked down the problem to tcsh. Just some follow up comments:

The server being headless doesn't stop qemu-dm from serving a vnc session on 
dom0, for windows or linux. Less work for you installing a vnc server in your 
domu, since it is already setup. I suppose this is just the way you are used 
to working.

Actually, It might well be easier come upgrade time to the next SuSE version, 
since you can use the install dvd, instead of 'yum update' or Yast2. (You 
have to redefine your repository/sources definitions, and probably manually 
download and install 'openSUSE-release' to get things started. I had to do 
something similar going from fedora fc7 -> fc8.)

Gnome has 'vino' which does the same thing.

Glad it is working for you now.
