Surely if you are mass creating vm's you use ks + cobbler and or spacewalk to do that instead af ISO file.
Both of those require you to deploy extra infrastructure, which isn't needed if using the ISO. Different approaches suit different people, and for many people the ISO installer images are the basis for their chosen approach.
Using a simple PXE boot requires the DVD (not net-install) if you want to point to a local repo to save bandwidth.
One day I hope just mounting it would be enough to reconfigure the PXE subsystem, but unfortunately, the pxelinux.cfg stuff seems very path dependant and all distros do things just different enough each release that it remains a manual process to update my PXE server for a new release of fedora/centos/ubuntu.
