Hello, i'm playing with ovirt-ansible-roles for building a standard configuration to be applied to all my ovirt setups. I downloaded ovirt-ansible-roles 1.1.1 from github and unpacked examples, playbooks and roles on a directory (/ansible/ovirt-ansible-roles/). I created then this playbook: ==8<==8<==8<==8<==8<== ovirt_infra.yml ==8<==8<==8<==8<==8<==8<=== --- - name: oVirt infra hosts: localhost connection: local gather_facts: false vars_files: - ovirt_infra_vars.yml - passwords.yml pre_tasks: - name: Login to oVirt ovirt_auth: url: "{{ engine_url }}" username: "{{ engine_user }}" password: "{{ engine_password }}" ca_file: "{{ engine_cafile | default(omit) }}" insecure: "{{ engine_insecure | default(true) }}" tags: - always - name: Generate Hosts list set_fact: hosts: "{{ hosts|default([]) + [ {'name': item.key, 'address': item.key, 'cluster': item.value.cluster, 'password': item.value.password|default('defaultpwd') } ] }}" with_dict: "{{ hosts_map }}" roles: - ovirt-infra post_tasks: - name: Logout from oVirt ovirt_auth: state: absent ovirt_auth: "{{ ovirt_auth }}" tags: - always ==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<=== file passwords.yml declares engine_password, ovirt_infra_vars.yml instead contain this vars: ==8<==8<==8<==8<==8<==8<== ovirt_infra_vars.yml ==8<==8<==8<==8<==8<=== --- engine_url: https://ovirtengine.intranet.company/ovirt-engine/api engine_user: admin@internal engine_insecure: True compatibility_version: 4.1 data_center_name: Default hosts_map: fltiovirt001.intranet.company: cluster: production clusters: - name: production cpu_type: Intel Westmere Family profile: production ==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<=== I did some pre-flight checks and everything seems ok: playbooks > ansible --version ansible 2.4.0.0 config file = /ansible/ovirt-ansible-roles/playbooks/ansible.cfg configured module search path = [u'/home/remixtj/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible python version = 2.7.5 (default, May 3 2017, 07:55:04) [GCC 4.8.5 20150623 (Red Hat 4.8.5-14)] playbooks > rpm -qa python-ovirt* python-ovirt-engine-sdk4-4.1.6-1.el7ev.x86_64 So i hope that everything goes smooth, but... playbooks > ansible-playbook ovirt_infra.yml [DEPRECATION WARNING]: The use of 'include' for tasks has been deprecated.
