Network issue at image creation

[KaZe]

Hello everybody,
    I'm working on this remix called RocketGatitos, I'm building it inside
a mock chroot, using livemediatools. I'm having troubles with network
but i cant find any solution:2017-02-09 19:08:46,613 INFO

livemedia-creator: (No hay dispositivos de red disponibles.)
which means "There is no available network devices"

Here is the kickstart file  and some logs:
Flatted ks: https://paste.fedoraproject.org/552009/86689119
program.log: https://paste.fedoraproject.org/552010/48668926
livemedia.log: https://paste.fedoraproject.org/552011/68930814

By the way I've made an script to automate the process, all is hosted on
github(https://github.com/piratas-ar/RocketGatitOS/tree/nuevo_metodo)

Basically it runs the next command inside the chroot:

livemedia-creator --ks "flat-${nombre_build}.ks" \
                  --no-virt  \
                  --resultdir=/results/${fecha_build} \
                  --logfile=/results/logs/${fecha_build}.log \
                  --project "${nombre_build}" --make-iso \
                  --volid "${nombre_build}-${version_fedora}" 		--iso-only \
                  --iso-name
"${nombre_build}-${version_fedora}-x86_64.iso" \
                  --releasever "${version_fedora}" \
                  --title "${nombre_build}-live" --macboot

Thanks and greets!
