[ubuntu-cloud] single server setup orchestra juju openstack

[Stefan]

Hello all,

Im new to cloud techniques and want to learn and play around with ubuntu 
cloud. I dont have 6 machines to play with, only one server, so I tried a 
single server setup. I searches around but can not find a usefull docu to run a 
single server with orchestra, juju and openstack on ubuntu 11.10. Some on 
openstack irc told me about http://devstack.org/. Okay this is running but 
installing or using orchestra and juju fail. I tried also cdinstall and 
packageinstall but nothing will work for me.

Now Im trying again using:
https://help.ubuntu.com/community/Orchestra/Juju

but I hang with:

root at monster:~# juju bootstrap
error: Environments configuration error: /home/stefan/.juju/environments.yaml: 
environments.orchestra.default-series: required value not found


Now Im despairing....
Can someone give me some hints to get a  
single server setup orchestra juju openstack running?

tia
