Hello, I have a powerfull Dell R810 here that I don't need to put into production for another week or two. I'm planning to take some time over the next few days to try a few things out on it. One of my objectives is to use something like Virtual box as I haven't used it yet. I'm going to attempt to learn how to provision up to a dozen or two Linux servers with Apache and Postfix running in a cluster. The purpose of this is to try to determine how attainable this is and to see if I still remember my Bash scripting etc. If you have any suggestions around Virtual box and what automation tool I should use I'm very interested. I could use Hyper-V or ESXI but as I'm very comfortable with both of these platforms I wouldn't gain as much as if I use something very different for a change. Darragh
