title: Ansible can't connect to Vagrant VM (Permission denied)
body: <p>I've put together a VM using Vagrant (Virtualbox is the provider) for a server I'm setting up. I can SSH into the VM using <code>vagrant ssh</code> and <code>ssh vmname</code>, but when I run <code>ansible-playbook -vvvv /path/to/playbook.yml</code>, I get a "permission denied" error when Ansible tries to connect to the VM.</p>
  
  <p>It's too long to post the results of running the playbook here, so I've <a href="https://pastebin.com/E9kM32C9" rel="nofollow noreferrer">uploaded it to Pastebin</a> instead. </p>
  
  <p>What am I doing wrong?</p>
