# XCP-ng: A turnkey open source virtualization platform
|
||||
|
||||
XCP-ng is a "reboot" of [old XCP](https://wiki.xen.org/wiki/XCP_Overview), which was ditched when XenServer was Open Sourced. Since XenServer 7.3 removed free features, [@olivierlambert](https://github.com/olivierlambert) ([Xen Orchestra](https://xen-orchestra.com) founder) decided to resurrect XCP, this time with a full community effort and not just a Citrix project.
|
||||
|
||||
## Goals
|
||||
* [What is XCP-ng?](#what-is-xcp-ng)
|
||||
* [Genesis](#genesis)
|
||||
* [Key points](#key-points)
|
||||
|
||||
* [Documentation](#documentation)
|
||||
* [Contribution & community](#contribution-and-community)
|
||||
* [Pro support](#pro-support)
|
||||
|
||||
1. The main goal is to be able to enjoy Xenserver power (XAPI/features) with a real community backed solution (not "one company dependent")
|
||||
2. We want this to be 100% compatible with XenServer (as possible): ie being able to transfer VMs from XS to XCP-ng and vice-versa
|
||||
3. Same for XAPI to be 100% compatible with Open Source management solutions (Xen Orchestra)
|
||||

|
||||
|
||||
## What is XCP-ng?
|
||||
|
||||
XCP-ng is a virtualization platform based on **Xen Source** and **Citrix® Hypervisor** (formerly XenServer).
|
||||
XCP-ng stands for **Xen Cloud Platform - New Generation** and is a *tribute* to the old Open Source project XCP, which was abandoned when XenServer was open-sourced in 2013.
|
||||
|
||||
### Genesis
|
||||
|
||||
* 2003 : Xen project birth, first open source hypervisor
|
||||
* 2007 : Xen Source Inc. acquired by Citrix, birth of XenServer (closed source)
|
||||
* 2010 : Citrix strategy focused on virtual desktop (XenApp/XenDesktop) instead of server virtualization
|
||||
* 2011 : XCP 1.0 (Xen Cloud Platform, Open Source XenServer)
|
||||
* 2013 : XenServer becomes Open (end of XCP). Birth of Xen Orchestra
|
||||
* 2017 (Dec) : Citrix changes their pricing strategy regarding XenServer and removes essential features from free XenServer versions. New features developed are (mostly) no longer open source
|
||||
* 2018 (Jan) : XenServer forked, birth of XCP-ng
|
||||
* 2019 (Jul): XCP-ng 8.0 is released
|
||||
|
||||
|
||||
### Key points
|
||||
|
||||
XCP-ng is a turnkey open source virtualization platform.
|
||||
|
||||

|
||||
|
||||
#### Platform
|
||||
|
||||
A combination of multiple components to deliver a cohesive solution
|
||||
|
||||
**Compute** + **Network** + **Storage** + **API** (Xen API) = **XCP-ng**
|
||||
|
||||
#### Open Source
|
||||
|
||||
XCP-ng is open source (mostly GPLv2), but also, all the components, documentation, repositories and dev process are publicly available and easily accessible.
|
||||
|
||||
#### Turnkey
|
||||
|
||||
* XCP-ng is intended to be easy to download and easy to install
|
||||
* We are aiming to have the largest possible hardware compatibility
|
||||
* XCP-ng embeds a complete API and comes with a friendly web-UI: [Xen Orchestra](https://xen-orchestra.com/#!/xo-home)
|
||||
|
||||
### Documentation
|
||||
|
||||
We have extensive documentation for the XCP-ng project available [here](https://github.com/xcp-ng/xcp/wiki)
|
||||
|
||||
### Contribution and community
|
||||
|
||||
XCP-ng has a living community that you can join on our [forum](https://xcp-ng.org/forum/).
|
||||
|
||||
The project is open to [contributions](https://github.com/xcp-ng/xcp/wiki/Development-process-tour), [bug reports](https://github.com/xcp-ng/xcp/wiki/How-to-report-bugs) and you can also [host a mirror](https://github.com/xcp-ng/xcp/wiki/Mirrors) for XCP-ng
|
||||
|
||||
### Pro support
|
||||
|
||||
For production environments and companies, we recommend obtaining pro support to cover your infrastructure. Pro support is delivered directly by the XCP-ng project dev team and pricing is per host, not per core!
|
||||
|
||||
Learn more about pro support for XCP-ng on the [dedicated website](https://xcp-ng.com/).
