To use livemedia-creator with virt-install you will need to install the
following packages, as well as have libvirtd setup correctly.

Existing spin kickstarts can be used to create live media with a few changes.
Here are the steps I used to convert the XFCE spin.
The docs/ directory includes two example kickstarts, one to create a live desktop
iso using GNOME, and the other to create a minimal disk image. When creating your
own kickstarts you should start with the minimal example, it includes several
needed packages that are not always included by dependencies.
Or you can use existing spin kickstarts to create live media with a few
changes. Here are the steps I used to convert the Fedora XFCE spin.
1. Flatten the xfce kickstart using ksflatten
2. Add zerombr so you don't get the disk init dialog
3. Add clearpart --all
4. Add swap and biosboot partitions

5. bootloader target
