FreeVSD

FreeVSD: "FreeVSD facilitates Linux virtual servers within a 'chroot' environment, allowing Web servers and other applications to be deployed and administered discretely, without compromise to security. Each virtual server has its own IP address(es), Apache webserver, and view of the process table. FreeVSD expands the Linux system by creating a pseudo-'super user' (admin) for each virtual server. The admin user has the ability to create extra POP3/FTP and Telnet users and also administrate vital services such as the webserver."
