I mount the ISO image using the loop back define (-o loop) and created a
virtual host whose DocumentRoot was the loop back mount point of the
DVD:

Line in /etc/fstab:

/distrocds/Fedora/Fedora-15-x86_64-DVD.iso /fc15x86_64  iso9660 ro,loop 0 0

http virthost spec:

<VirtualHost *:80>
ServerName fc15.deepsoft.com
DocumentRoot /fc15x86_64
<Directory /fc15x86_64>
AllowOverride all
Options FollowSymLinks
</Directory>
</VirtualHost>

This seems to work, so long as one does not select random unseen options
in the GUI installer... :-(
