I just figured out the issue - at least in the LAMP appliance.  The cdrom is not mounted into the file system.  The cd is "in the drive" - but the drive is not actually mounted.  In the command line,  you will need to enter: mount /dev/cdrom /cdrom

 This will put the cdrom into the filesystem so you can then go through the installation.  However, it seems I have into insall a zip utility to do the install.  If it's not one thing, it's two!

Hope that helps.
