title: Unable to use new Vagrant install - Error while connecting to libvirt
body: <p>Regardless if I have a Vagrant file or if one doesn't exist and I create my own with <code>vagrant init</code> (which works btw) I get an error when trying to do this:</p>
  
  <pre><code>vagrant up
  </code></pre>
  
  <p>The error is:</p>
  
  <pre><code>1: from /usr/share/rubygems-integration/all/gems/vagrant-libvirt-0.0.43/lib/vagrant-libvirt/driver.rb:40:in `connection'
