VulcanSphere (talk | contribs) Adding short description: "OS-level virtualisation" (Shortdesc helper) |
Guy Harris (talk | contribs) I've no idea whose invention "S390/X" is, but, unlike the other XXX/64, which at least suggest that it's the 64-bit version of XXX, "S390/X" doesn't do that. "s390x" does, at least in the context of Linux. And, if it's 64-bit, link to z/Architecture, which is the name for the 64-bit version of System/3x0, not to anythign 32-bit. |

'''Linux-VServer''' is a [[virtual private server]] implementation that was created by adding [[operating system-level virtualization]] capabilities to the [[Linux kernel]]. It is developed and distributed as [[open-source software]].
==Details==
The project was started by [[Jacques Gélinas]]. It is now maintained by Herbert Pötzl. It is not related to the [[Linux Virtual Server]] project, which implements network [[Load balancing (computing)|load balancing]].
Line 29 ⟶ 32:
Virtual private servers are commonly used in [[web hosting]] services, where they are useful for segregating customer accounts, pooling resources and containing any potential security breaches. To save space on such installations, each virtual server's file system can be created as a tree of [[copy-on-write]] [[hard link]]s to a "template" file system. The hard link is marked with a special filesystem attribute and when modified, is securely and transparently replaced with a real copy of the file.
Linux-VServer provides two branches, stable (2.2.x), and devel (2.3.x) for 2.6-series kernels and a single stable branch for 2.4-series. A separate stable branch integrating the [[grsecurity]] patch set is also available.
