----------- cut --------------------------------

this is a hosts.j2 tempalte file that goes under tempalte folder.

i call the role like this

---
- name: Cleanup VM
  hosts: cleanup
  remote_user: root
  roles:
    - cleanup

- name: Install Common
  hosts: all
  remote_user: root
  roles:
    - common

- name: Install hosts configuration
  hosts: all
  remote_user: root
  roles:
    - hosts

(...)

i have other stuff there but it breaks on the hosts role.
