Welcome to Linux-VServer.org 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. This site contains information relating to the use and development of virtual servers based on Linux-VServer. This particular virtual server model is implemented through a combination of "security contexts", segmented routing, chroot, extended quotas and some other standard tools. Note: If this isn't what you are looking for, maybe Linux Virtual Server is.
