Open Stack

Hi Jagga,

You can use packer. In our case, we needed some special images with LVM, so
I decided to use packer to create qcow2 images. Have a look here:
https://github.com/jriguera/packer-ironic-images/tree/master/ubuntu

You have to change the cloud-init configuration to add the OpenStack
metadata provider.

Regards,
