This is the playbook currently in development to deploy oVirt.
This playbook uses ovirt roles that are included in Ansible Galaxy. The following is a summary of this page.
Install the roles with
ansible-galaxy install ovirt.ovirt-ansible-roles
The easiest way for Ansible to find these roles is to change the roles directory with:
sed -i 's|#roles_path = /etc/ansible/roles|roles_path = /etc/ansible/roles:/etc/ansible/roles/ovirt.ovirt-ansible-roles/roles|' /etc/ansible/ansible.cfg
