CESNET has been using OpenNebula in academic/research environment since 2011. Over the years, we had to develop a bunch of small(ish) tools and helpers to make our lives easier. This talk will present a carefully selected subset of tools that we found the most useful, educational, or interesting. It will also reminisce about tools that are long gone, no longer necessary thanks to continuing OpenNebula development. YouTube: https://youtu.be/FBmZh92mEq4
