本文详细介绍了开源虚拟化技术Xen、基于Xen技术的商业套件XenServer以及全功能虚拟化平台XenCloudPlatform（XCP）之间的区别。Xen作为纯虚拟化内核，提供基本的虚拟化功能；XenServer在此基础上增加了管理控制台、工具集等，功能更全面；XCP则是一个完整的虚拟化解决方案，具备与XenServer相当的功能，且易于上手。

xen，xenserver，xcp的区别

Xen: The open source, completely free granddaddy of the Xen family (which at one time had many children, most of whom are now gone.) Xen is different from all of its competitors in that it is a hypervisor ONLY and not a virtualization ecosystem (no management console, no extra features, no nothing.) It’s just a tiny little hypervisor. This is confusing because we lump Xen with HyperV, for example, but it is not an apples to apples comparison. Xen is like the hypervisor inside HyperV that no one even knows the name of.

XenServer: The primary commercial virtualization suite built on technologies derived from Xen. XenServer is an “older” version of Xen with some features removed and other featurs hidden behind “add ons.” So XenServer is far less functional than Xen and is not completely free (it can be, but many features are not.) XenServer is a full suite with all of the nice console and tools, APIs, etc. Much more user friendly than Xen and requires no core OS knowledge to get it working unlike Xen that requires you to really know the Dom0 environment well.

XCP: Xen Cloud Platform. XCP is a full virtualization suite based on Xen. It uses real Xen and combines in all of the other components needed to be a full suite just like XenServer, vSphere and HyperV. It is open source and comes from the Xen people. Today, when people talk about Xen, they mostly talk about XCP as XCP is the apple to apple with the other products and not just the hypervisor. You lose no functionality going with XCP over Xen on its own but it is far easier. XCP is designed to be interoperable with most, if not all, APIs from XenServer so that they can share tools giving XCP a lot of important options.
