the physical machine where you will run the virtualization software and
boot up the VM. The terms "guest machine" or just "VM" refer to the
virtual machine itself -- the thing where you actually do the tutorial
-and that you boot up on the "host machine".

-Also, to reduce download size, the Tutorial VM just includes a minimal
-command-line environment. In general, it is expected that people will
-boot up the Tutorial VM on their main desktop (the "host machine" using
-the terminology above) and then use that main desktop machine to SSH and
-web browse into the "guest VM" as they work through the tutorial. If
-you wish to install X-Windows (or any other packages), just use the
-C<aptitude> (or C<apt-get>) Debian commands.
+(and that you boot up on the "host machine").
+B<Note:> Throughout the tutorial, we will shows the UNIX shell prompt
+as "C<$>". If you are using Tutorial VM, the prompt will really be
+"C<root@catalyst:~#>", but we will keep it short (and also use "C<$>" in
+lieu of "C<#>", since "C<#>" looks too much like a Perl comment).
