I am running <code>vagrant up</code> command on Windows 7 box (<code>Vagrantfile</code> exists in work dir) and getting the message: <blockquote> Provider 'virtualbox' not found. We'll automatically install it now... </blockquote> Virtual box has been installed and <code>vbox_install_path</code> env variable is correctly set. Working in intranet, there is no way to automatically install VB from the internet.

Vagrant 1.8.4 and older are not compatible with the VirtualBox 5.1.x. Vagrant 1.8.5 has been released already and it supports the VirtualBox 5.1.x.

Sorted out. Vagrant 1.8.4 does not work with VirtualBox 5.1.0 (on Win7 at least). Fixed after VB version was changed to 5.0.20
