So we'd have a command line tool that basically templates a few values
into a stock image.xml file ?

No, there's no tool currently that goes from libvirt XML -> image XML,
though it wouldn't be hard to write (especially given the virt-convert
work that John Levon is doing). As with all VM conversions, the real fun
is in the disk conversion - for cobbler, you'd need file-based disks, so
you'd need to do some conversion if the VM is running off of LVM volumes
etc.
