If using a VM:
# on cobbler server
cobbler image add --name=livecd --path=nfs://server/path/to/livecd.iso
# on host system
koan --virt --virt-type=qemu --image=livecd
This all goes through the virtinst libraries to make sure the correct
arguments are used. If that /still/ fails, we can debug this.
The process for PXEbooting that still involves "cobbler distro add" and
not "image add" based on the Wiki link "AllAboutImages" I posted
yesterday.
Yep, we're going to want to get partimage packaged for Fedora.
