Initially, I planned to publish all how-to s for advanced network configurations for virtual machines in one article. However, I am unstoppable when it comes to writing, and the article became quite long. So, I decided to split the theory from the hands-on configurations, XML/Shell scripting, etc. You might think you don’t need to read this, but I strongly discourage you from jumping directly to the next article and blindly copying my configurations without understanding what you’re doing.
