  <p>I am running the latest version of <code>VirtualBox</code> running <code>Ubuntu 14.04.4</code>. Then, I am running a Vagrant Box inside the virtualbox which gives me that error. My virtualization is enabled in the <code>BIOS</code> and my processors are able to support virtualization. I read in another thread that nested virtualization is possible if we change vb.cpus to 1. However, I think the configuration file has changed and I can't find the provider block in my Vagrant file. Does anyone know how to solve this error?</p>

  <p>Edit: Clarification on the setup. My host is running 'Windows 10' which has a virtualbox open. This virtualbox is running Linux 'Ubuntu 14.04.4' 64bit. From here, I ran the command 'vagrant box add laravel/homestead' which creates a virtualbox Ubuntu 32 bit. Then, I run the command 'vagrant up' which gives me the above error. I'd also like to add that the acceleration tab is greyed out inside my virtualbox settings.</p>
