OpenVZ is used for Virtualization and is both light weight (minimal software on the host, guests have small footprints on the hard drive, and minimal use of RAM) and fast (native speed).

Although I have been using Ubuntu as an OpenVZ guest, I have decided to give Debian a try.

Debian has a few advantages and Debian Squeeze seems “stable enough”.
