OpenVZ is an Operating System-level server virtualization
solution, built on Linux. 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. See OpenVZ Wiki (http://wiki.openvz.org/) for more information. (From the Openvz.org homepage)
