I use a script to do this occasionally. You can find the link to the source for that at [1]. I'll try
to put out a blog showing how to use this sometime soon. Generally the steps are

- set location for install media [2]
- pull down kickstart (start with the fedora one [3] and update ostreesetup line [4])
- update variables in script
- run virt-kickstart.sh
- cp qcow somewhere else
- delete vm in libvirt (virsh undefine)
