Note that on that page I've rolled several Debian guest systems together 
into one section, showing appropriate differences in configuration files 
etc. Some of the scripts I've given are probably a bit idiosyncratic, 
but they're what I've found has worked for me over the 5+ years I've 
been using Qemu on various systems.

Most guest systems are built (not by me) to expect that they can display 
their console in an xterm. I normally start up in a VNC session, then 
log in over SSH.

Please yell if anything's unclear.
