**Note**: There are more things needed for **ubuntu ppc64le** osimages:
For ubuntu ppc64le, the shipped initrd.gz within ISO is not supported to do network booting. In order to install ubuntu with xCAT, you need to follow the steps below to complete the osimage definition.

[ubuntu 14.04.1]: http://ports.ubuntu.com/ubuntu-ports/dists/$(lsb_release-sc)/main/installer-ppc64el/current/images/netboot/
[ubuntu 14.04.2]: http://ports.ubuntu.com/ubuntu-ports/dists/trusty-updates/main/installer-ppc64el/current/images/utopic-netboot/
[ubuntu 14.04.3]: http://ports.ubuntu.com/ubuntu-ports/dists/trusty-updates/main/installer-ppc64el/current/images/vivid-netboot/
* Mount mini.iso ::
mkdir /tmp/iso
mount -o loop mini.iso /tmp/iso
* Copy the netboot initrd.gz to osimage ::
mkdir -p /install/<ubuntu-version>/ppc64el/install/netboot
