I like playing with different distributions of Linux, and am pretty curious about distributions that are geared towards netbooks. I was curious about checking out the latest version of Ubuntu Netbook Remix, but I wanted to check it out in VMWare Workstation before actually installing it on my netbook. Unfortunately, the installer is intended to be copied to a USB thumb drive and installed from there. This doesn't work in VMWare.
This page has instructions on how to install UNR in a virtual machine. These instructions create a disc image that can be mounted our burned to disc.
