body: <p>I want to set default verbosity level in ansible. I set <code>default_verbosity=1</code> in <code>anisble.cfg</code> but this is not working. If I set environment variable <code>ANSIBLE_VERBOSITY=1</code> then I can see verbose level 1 output for my running tasks. </p>
  
  <p>As per my current requirement, I want to set this value in ansible.cfg.</p>
