<p>I am a beginner to Kubernetes and starting off with <a href="https://kubernetes.io/docs/tutorials/hello-minikube/#create-your-node-js-application" rel="noreferrer">this</a> tutorial. I installed <a href="https://www.virtualbox.org/wiki/Downloads" rel="noreferrer">VM</a> and expected to be able to start a cluster by using the command: </p>

<pre><code>minikube start
</code></pre>

<p>But I get the error: </p>

<pre><code>Starting local Kubernetes v1.10.0 cluster...
Starting VM...
E0911 13:34:45.394430   41676 start.go:174] Error starting host: Error 
creating host: Error executing step: Creating VM.
: Error setting up host only network on machine start: The host-only 
adapter we just created is not visible. This is a well known 
VirtualBox bug. You might want to uninstall it and reinstall at least 
version 5.0.12 that is is supposed to fix this issue.
</code></pre>

<p>It says that it is a well known bug in Virtualbox but I installed its latest version. Any ideas?</p>

Satyajit Das
<p>Figured out the issue. VirtualBox was not installed correctly as Mac had blocked it. It wasn't obvious at first. </p>

<ul>
<li><p>Restarting won't work if VirtualBox isn't installed correctly. </p></li>
<li><p>System Preferences -> Security &amp; Privacy -> Allow -> Then allow the software corporation (in this case Oracle)</p></li>
<li><p>Restart </p></li>
</ul>

<p>Now it worked as expected.</p>
