Why do people value that so much? I really don&#x27;t care if a tiny VMis running in the background. 
Also, running that VM gives me more confidence that it will also run on the production machine (since they use the same kernel and the same docker version).<p>The only problem I had with docker was that I did not use to support shared volumes that are outside the home folder on Mac (I think they changed that now, but I&#x27;m not sure).
