    I have been looking for this article. I was wanting to set up a virtual lab to practice for my RHCE and this article totally covers the pieces I was missing to make it work.

    Thank you.

    Any chance you can add an index to all of the articles in this series, linking them together?

    Would make it easy to navigate in order, rather than having to search the site and piece the order together.

    Not critical, but would put the series together. Good write-ups!

      I will get an index and next and previous in series links added so that users can navigate easily.
