If you do not have the VGA font installed, you will need
to install it first (you can check this by skipping to
step 6, and checking whether running the VM gives an error
message). You will only have to do this once. The VGA font
resides in misc/vga.pcf. In order to install it, you'll need
to be root. Put it in the X fonts 'misc' directory and do
what is necessary on your system to rebuild that font
directory and let your system know about the update.
For example, on Mandrake 7.1:
user> su
root> cp misc/vga.pcf /usr/X11R6/lib/X11/fonts/misc
root> gzip /usr/X11R6/lib/X11/fonts/misc/vga.pcf
root> chmod ugo+r /usr/X11R6/lib/X11/fonts/misc/vga.pcf.gz
root> mkfontdir /usr/X11R6/lib/X11/fonts/misc
root> killall -HUP xfs # notify font server of the change
root> xset fp rehash
root> exit
