XCP Overview

What is XCP?

Xen Cloud Platform The Xen Cloud Platform (or XCP) is a turnkey virtualization solution that provides out-of-the box virtualization and cloud computing. XCP includes the Xen Hypervisor, the enterprise ready Xen API toolstack with functionality such as

• the capability to manage pools of host systems
• support for advanced storage repositories
• support for mutli-tenancy
• support for SLA guarantees
• and detailed metrics for consumption based charging and more,

and pre-integrated network and disk functionality such as Open vSwitch.

XCP and XenServer

XenServer is Citrix' commercial distribution of XCP. XCP contains a subset of features of XenServer functionality: for a detailed comparison see XCP/XenServer Feature Comparison.

Flavours of XCP

XCP comes in two flavours:

• XCP ISO : Installs like XenServer and comes with the same drivers as XenServer, is mostly the same code as XenServer and is based on a specific version of Xen and an optimized CentOS 5 Dom0 Kernel
• XCP-XAPI Packages : These are XCP packages that are delivered in Linux distros (currently only Debian and Ubuntu 12.04 LTS or newer) and are installed via your host OS'es package manager

The table below compares the two flavours:

XCP ISO	XCP-XAPI Packages
Black-box style appliance	Linux packages (assemble your own system)
CentOS 5.x based Dom0	Most components provided by distro
Managed using XAPI	Managed using XAPI
Supports most XenServer features	Some restructions
Supports most storage repository (SR) types	Limited set of shared SR types
Only works with supplied CentOS Dom 0	Support for Debian/Ubuntu host OS (plans for Fedora and other distros)
Hard to customize	Easy to customize
Hard to build from source	Easy to build from source

XAPI Toolstack and Command Line

One of the core differences between Xen and XCP is the XCP Toolstack (XAPI) and the commandline console (XE). For a general overview of toolstacks supportedf by Xen see the Xen Toolstack Overview.
