Hi,
The 4MLinux Server has recently been deeply modified by me. I dare say that this now the lightest and the fastest server suite available on the market. For example,
http://server.4mlinux.com is setup on KVM with 512 MB of RAM. I have no problem to start X and run Chromium (web browser) inside this server. The browser can be used to access the 4MLinux Server Web Interface.
The recently updated documentation is available here:
