I chose OpenVZ over other virtualizations because OpenVZ is fast and efficient. It is in fact the most fast an efficient because it sacrifices some of the features of true virtualization. It's Linux only and has a single kernel. But my needs are Linux only and OpenVZ has almost no overhead at all. It doesn't leave memory fragmented into virtual machines that never use all their ram. Instead the memory limits are just caps and memory usage depends on what you run.It's fast, it's simple, and it just works.
