Hello,

 I was having a look at the ansible playbooks to autmate the installation of ovirt-engine on a remote host here at https://github.com/rhevm-qe-automation/ovirt-ansible/ specifically the role engine-setup. I was curious where this jinja variable {{ansible_fqdn}} gets set.  I could not see it being assigned in the playbooks. Or do we set it during the playbook execution as a command line arg?


The ansible_fqdn is taken from ansible facts. You can evaluate it on the target host by running (replace target_host_name with the proper host name or localhost for testing only):
ansible target_host_name -m setup -a 'filter=ansible_fqdn'

You can read more about jinga filters by facts here:
http://docs.ansible.com/ansible/playbooks_variables.html#jinja2-filters

Also, you can read more about fact/variables precedence here:
