docker : When creating a machine, VT-X/AMD is enabled yet
<p>I'm going through this tutorial </p>

<p><a href="https://realpython.com/blog/python/dockerizing-flask-with-compose-and-machine-from-localhost-to-the-cloud/" rel="noreferrer">Dockerizing Flask With Compose and Machine - From Localhost to the Cloud </a></p>

<p>When trying to create a virtualbox with the command below </p>

<pre><code>docker-machine create -d virtualbox dev;
</code></pre>

<p>I have the following error</p>

<blockquote>
  <p>Error creating machine : Error in driver during machine creation. This computer doesn't have VT-X/AMD enabled. Enabling it in the BIOS is mandatory </p>
</blockquote>

<p>(Addendum: I'm running an ubuntu image on a virtual box. The physical host is a windows machine. The VT <code>VT-X/AMD</code> is enabled both , in the bios and in the virtualbox.)</p>

<p>Reading here and there, it seems to be a normal behavior because I'm trying to create a virtualbox within a virtualbox -> <a href="https://github.com/docker/machine/issues/2256" rel="noreferrer">Click here for the explanation</a> </p>

<p>What command should I use instead of <code>docker-machine</code> ?</p>

<p>Any insights are more than welcomed ...</p>

<p><strong>Update</strong>: I've asked 3 additional questions to @VonC after his initial answer. Please find the questions below , <em>in italic</em></p>

<p><em>1) How should I make the virtualbox and the docker config see that new "virtualbox"?</em> </p>

<p><em>2) Will the ubuntu box, be able to do the docker-compose and build the container on that host?</em></p>

<p><em>3) If I'm pulling an image like debian, how can I use it as a machine and build an container on top of it?</em> </p>
