TODO: add a section about uploading images (note, very important to specify image format)
CERN docs on OpenStack, might be helpful https://clouddocs.web.cern.ch/clouddocs/
Add a section about CloudInit? http://cloudinit.readthedocs.io/en/latest/
Want some clarity about the differences between an image, a snapshot, and a bootable volume, as well as "Boot from image (creates new volume)" and "Boot from volume snapshot (creates new volume)".
Note about cloud init, if you are dynamically creating your cloud init file, say through heat, then you can see the result that the particular VM sees by going to:
[name@server ~]$ curl -s http://169.254.169.254/openstack/latest/user_data
from the particular VM in question.
