Alan Renouf has completely open-sourced one of the most popular virtualization management tools out there – VMware Community PowerPack. This is a free custom add-on (also known as Virtu-Al PowerPack ;)) for PowerGUI/VESI and it has already been downloaded more than 10,000 times!
For all this time, the PowerPack (as actually any PowerGUI pack) has been open source in the sense that you could see the PowerShell code behind it and modify it for your personal needs. What is changing is that now the pack itself becomes a community effort and you can (in fact, in my opinion, should ;)) contribute back to make it better.
