title: VirtualBox and Vagrant
body: <p>I have tried installing latest versions of VirtualBox and Vagrant, but I keep receiving the error message below when trying to run vagrant. How can I find the problem and correct it?</p>
  <pre><code>No usable default provider could be found for your system.
  
  Vagrant relies on interactions with 3rd party systems, known as
  &quot;providers&quot;, to provide Vagrant with resources to run development
  environments. Examples are VirtualBox, VMware, Hyper-V.
  
  The easiest solution to this message is to install VirtualBox, which
  is available for free on all major platforms.
  
  If you believe you already have a provider available, make sure it
  is properly installed and configured. You can see more details about
  why a particular provider isn't working by forcing usage with
  `vagrant up --provider=PROVIDER`, which should give you a more specific
  error message for that particular provider.
