[Server-devel] XO Visualization Feature

[Anish Mangal]

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: [127.0.0.1] => (item=couchdb,curl)

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

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]

Any pointers would help.
