Vagrant uses Virtualbox to manage the virtual dependencies. You can directly download virtualbox and install or use homebrew for it.
$ brew cask install virtualbox
Now install Vagrant either from the website or use homebrew for installing it.
$ brew cask install vagrant
Vagrant-Manager helps you manage all your virtual machines in one place directly from the menubar.
$ brew cask install vagrant-manager
Usage Add the Vagrant box you want to use. We'll use Ubuntu 12.04 for the following example.
$ vagrant box add precise64 http://files.vagrantup.com/precise64.box
You can find more boxes at Vagrant Cloud
Now create a test directory and cd into the test directory. Then we'll initialize the vagrant machine.
$ vagrant init precise64
Now lets start the machine using the following command.
$ vagrant up
You can ssh into the machine now.
$ vagrant ssh
Halt the vagrant machine now.
$ vagrant halt
Other useful commands are suspend, destroy etc.
