I want to install openstack using triple o installation. I have installed the undercloud using packstack method using the below command.

packstack --allinone --provision-demo=n  --os-neutron-ovs-bridge-mappings=extnet:br-ex  --os-neutron-ml2-type-drivers=vxlan,flat


Now as the link at http://docs.openstack.org/developer/t... under the "Undercloud Data Preparation" section, talks that one must download the images for the undercloud beforehand. The document lists two different methods 1) Download these qcow2 images and upload them to the glance of the undercloud OR 2) Use disk-image-builder to create the images.

I was wondering if any of you guys know of a link from where we can actually directly download these pre-built images?

Also, if someone is aware, please point to the link that lucidly explains a process of creating these images manually using disk-image-builder
