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.
For a feature matrix, see XCP Release Features.

Integration with Cloud Orchestration Stacks
Introduction to the XCP Architecture
- Download the ISO
- Boot/install it on a fresh machine (likely using the whole available hard drive)
- Configure the network from the very brief administrative interface that stays on the screen after installation
- Manage the server over the network using CLI tools, or a GUI management tool.
- Now you can start installing and running supported guest VMS using paravirtualization or hardware virtualization.
- You can run hardware virtualization (HVM) guests only if your machine has the necessary hardware to support it.
- Otherwise any CPU can run paravirtualization (PV) guests, it just means you're limited to the guest OSes and kernel versions that specifically support PV (e.g. Ubuntu 10.04 for example supports PV).
There's a great article here that shows screen-shots all the way through the installation process: http://www.dedoimedo.com/computers/xen-cloud.html
From the Debian/Ubuntu Repos
You can install xapi, the XenAPI management server, on a Debian or Ubuntu system.
- Install Debian, or Ubuntu, using your preferred method
apt-get install xcp-xapi
See Installing Xapi on a Debian-based system for more information.
The Xen community are helpful and friendly people. We are here for you. There are several ways to get help and keep on top of what is going on!
- Read News!
- Read Documentation!
- Contact other users, to ask the questions and discuss Xen, XCP or other Xen related projects
- Xen Home page aggregates selected news stories and blog posts
- The Xen Blog covers technical and community related stories
- xen-announce mailing list is a low frequency mailing list for important announcements
Documentation for projects hosted on Xen.org is available on the Xen Wiki. Our wiki is active and community maintained. It contains a lot of useful information and uses categories extensively to make it easy to find information. You may also want to check:
Search Mailing Lists All Xen.org mailing lists are archived using the MarkMail system at xen.markmail.org. Before you ask a question, it is worth checking whether somebody else has asked the question before
Main Mailing Lists Xen.org maintains a number of mailing lists for users of Xen, the Xen Cloud Platform and other projects. English is used by readers on this list.
- xen-users is the list for technical support and discussions for the Xen hypervisor. If you are not sure where your question belongs start here!
- xen-api is the list for technical support and discussions for the Xen Cloud Platform (XCP).
- xen-arm is the list for technical support and discussions for the Xen ARM project.
Internet Relay Chat (IRC) is a great way to connect with Xen community members in real time chat and for support.
- ##xen is the channel for technical support and discussions for the Xen hypervisor. If you are not sure where your question belongs start here!
- Check out our IRC page if you are not familiar with IRC.
There are a number of other places, where you can get help on Xen and XCP. For example:
- Xen Questions on serverfault
- XCP & XenServer Questions on serverfault
- Many Linux Distributions that support Xen have a dedicated list - see the table in this link
If you find a bug, you can report bugs against Xen, or the Xen Cloud Platform. Before you raise a bug, please read Reporting Bugs against XCP!
