Open Stack

Hi,

can you describe your installation which is used for cluster creation? I
mean can you provide some details on what node groups were created, cluster
templates and so on. In addition, I saw that you filled the bug:
https://bugs.launchpad.net/sahara/+bug/1600666 Have you solved that issue?
What strategy your are using right now in terms of floating ips and
namespaces?
