Linux-VServer provides virtualization for GNU/Linux systems. This is accomplished by kernel level isolation. It allows to run multiple virtual units at once. Those units are sufficiently isolated to guarantee the required security, but utilize available resources efficiently, as they run on the same kernel.

OpenVZ is a Linux virtualization solution. It creates a virtual server strating at the init script (the kernle is shared). OpenVZ creates isolated, secure virtual environments — VEs (otherwise known as virtual private servers, or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each VE performs and executes exactly like a stand-alone server; VEs can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

Server clusters and server virtualization may be two different animals, but they're animals that can work well together in a data center, says Hakon Bugge, founder and CTO of Scali Inc., a Linux clustering systems provider in Marlborough, Mass.

Xen is a virtualization system for linux. It allow to run several virtual machines on a single hardware machine, or run a single virtual machine on many physical machines?

This is a tutorial to build a virtualized linux system based on openVZ
