Hi Martin,

Thanks for submitting the feature. I was experimenting with trying to
install the xovis system through the ansible task. The first time, it got
stuck here...

TASK: [xovis | Install Couchdb and other necessary packages]
changed: [] => (item=couchdb,curl)

TASK: [xovis | Allow access to Couchdb from other hosts]
changed: []

TASK: [xovis | Enable Couchdb service]
changed: []

TASK: [xovis | Add admin user]
failed: [] => {"changed": true, "cmd": ["curl", "-X", "PUT", "", "-d", "\"admin\""], "delta":
"0:00:00.556050", "end": "2014-06-01 06:00:26.021649", "item": "", "rc": 7,
"start": "2014-06-01 06:00:25.465599"}

FATAL: all hosts have already failed -- aborting

I ran it again, and the playbook went beyond this step fine, but now is
stuck while trying to fetch the database dump getting a 403 ... log below...

TASK: [xovis | Add admin user]
changed: []

TASK: [xovis | Remove Couch database if it already exists]
changed: []

TASK: [xovis | Create Couchdb database]
changed: []

TASK: [xovis | Install the latest XOstats script]
changed: []

TASK: [xovis | Install xovis and xostats python dependencies]
changed: []

TASK: [xovis | Fetch database dump to the server]
failed: [] => {"changed": true, "cmd": ["wget", "-O",
"/opt/xovis/xovis.json", "https://s3.amazonaws.com/xovis/xovis.json"],
"delta": "0:00:06.945208", "end": "2014-06-01 06:06:41.045964", "item": "",

Any pointers would help.
