I think we're not entirely on the same page here.

If we want to make the install process a no-questions-asked, background
thing, it's probably not going to involve booting from the ISO (unless
there is a simple way to provide preseed files through kvm that I have
not thought of), but rather some variant of debootstrap + additional
configuration magic. This is what my vm-builder script does now.

debootstrap can use a local mirror, so what I'm thinking is to add a
script that can take the CD and turn it into a local mirror for
debootstrap to use.
