What we install in Virtualbox using Vagrant?
<p>I just started learning <a href="https://www.vagrantup.com/" rel="nofollow">Vagrant</a> and succeeded in using it. I went through this <a href="http://www.vagrantbox.es/" rel="nofollow">vagrantbox.es</a> where we "download" the "templates".</p>

<p>I have some doubts and would be great if anyone can explain me:</p>

<p>1) <code>Vagrant</code> --> My understanding is t hat it helps in automating installing the Virtual machines in Virtualization software like Virtualbox. Is this correct?</p>

<p>2) Now, as per the instructions that I followed in one of the video tutorials, we need to 'download' the VM, from <a href="http://www.vagrantbox.es/" rel="nofollow">this </a> link.</p>

<p>My doubt is what are we downloading from the link in point #2? Using Vagrant, are we downloading a VM (and which gets installed into Virtualbox, for example?). Can't we use any .iso image and let vagrant install it? I am bit confused here.</p>

<p>Can anyone who has used vagrant explain what exactly are we downloading?</p>
