Where can I find ready-to-use virtual machines?

Solution 1:

If you are open to trying a different virtualization software, I recommend http://www.virtualbox.org.

You could also find some great virtual appliances ready for download from http://virtualboximages.com/

Good luck!

The VMWare Virtual Appliance Marketplace has many pre-built appliances: http://www.vmware.com/appliances/

There are some in the answers to this question: Pre-installed Linux for Web Developers?

Then there's BitNami offering various ready-to-go VMs for various purposes: http://bitnami.org/

And the VMWare Applicance market
