Free Bits

There are many free tools and utilities available on the internet that allow you to configure and manage your VMware environment. This page is not a full listing but it helps you getting started with finding the tools and utilities that might be useful for your environment.

Flings by VMware Labs

The engineers at VMware work on tons of pet projects in their spare time, and are always looking to get feedback on their projects (or “flings”). Why flings? A fling is a short-term thing, not a serious relationship but a fun one. Likewise, the tools that are offered at the VMware Labs web site are intended to be played with and explored. None of them are guaranteed to become part of any future VMware product offering and there is no support for them. They are, however, totally free for you to download and play around with them!
