OpenVZ is a modified Linux kernel with additional support for OpenVZ Virtual Environments (VE, also known as VPS). VEs are isolated, secure environments 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. Due to a single kernel model, OpenVZ has native performance and very high density. It is the core of Virtuozzo. License: GNU General Public License (GPL) Changes:
