title: Should Vagrant require sudo for each command?
body: <p>My question in short: I run into permissions error every time I execute any Vagrant command without 'sudo' - from <code>vagrant up</code> to <code>vagrant provision</code>. Is this expected behaviour?</p>

  <h2>Sidenote</h2>
  
  <p>Besides the permission error mentioned above, I receive a lot of other various errors and timeouts, so I suspect that there may be something fundamentally wrong with my Vagrant installation (maybe permission wise?). But as I am clearly no Unix ninja, I'm not really sure what is the problem here. Most of the errors, according to Google, are pretty common and can be caused by multiple reasons (such as "Timed out while waiting for the machine to boot." or else).</p>
  
  <p>Recently, after xth trail, I was able to successfuly <code>vagrant up</code>. I received this error: The private key to connect to the machine via SSH must be owned by the user running Vagrant." After running ... </p>
  
  <pre><code>sudo chown root insecure_private_key
  </code></pre>
  
  <p>... my Vagrant seems to act little more stable.</p>
  
  <p>This just a sidenote to provide some (pretty localized) context to my question, so feel free to edit/delete it, if it does not provide any value.</p>
