[cobbler] cobbler import fedora 21 failed

Hello, I'm trying to import the fedora 21 distro from rsync or dvd with: cobbler import --path=/mnt/iso --name=fedora21 --arch=x86_64 but it fails with !!! TASK FAILED !!! After, I tried to add the distro uploaded before with: cobbler distro add --name=fedora21-x86_64 --ksmeta="tree=ftp://nas-deploy.ll.iac.es/media/fedora/releases/21/Fedora/x86_64/os/" kernel=/var/www/cobbler/ks_mirror/fedora21-x86_64/images/pxeboot/vmlinuz initrd=/var/www/cobbler/ks_mirror/fedora21-x86_64/images/pxeboot/initrd.img --arch=x86_64 --breed=redhat --os-version=fedora21 and it seems to be ok, but if I do: cobbler distro list or cobbler report, no distros appear... Is there anyone could have imported the fedora21 distro? how? Thank you and best regards, Estrella -- Estrella Zatón Martín Ingeniero del GSC. Servicios Informáticos Comunes.
