Xen is open source virtualization software that allows multiple operating systems to run simultaneously on a single hardware system. Xen Cloud Platform (XCP) is an open source distribution of XenServer developed by Citrix. XCP 1.1 provides a virtualization stack for server virtualization and is distributed as a closed appliance with CentOS and networking/storage support. Future releases of XCP will focus on features like disaster recovery, GPU passthrough, and support for new guest operating systems. The Kronos project aims to make the XenAPI toolstack compatible with other Linux distributions beyond CentOS.

2. XEN – xen.org
Xen é um software livre de virtualização para as arquiteturas
x86, x86-64, IA-32, IA-64 e PowerPC. Xen permite a execução
de vários sistemas operacionais, simultaneamente, sobre um
mesmo hardware.
Xen foi originalmente desenvolvido como um projeto de
pesquisa na Universidade de Cambridge, liderado por Ian Pratt,
fundador da XenSource, Inc.
Em 15 de agosto de 2007, a XenSource foi adquirida pela Citrix
System Inc. pelo valor de 500 milhões de dólares.
A Citrix agora suporta o desenvolvimento do projeto open source
e vende também uma versão "empresarial" do software.
O primeiro lançamento público do Xen foi disponibilizado em
2003.

3. Surgimento XEN CLOUD PLATFORM
A Citrix já vinha sinalizando à algum tempo seu interesse em
abrir por completo sua solução de cloud (XenServer).
Em 2009 foram disponibilizadas diversas funções enterprise do
XenServer sem custo para utlização.
Simon Crosby, CTO de virtualização da Citrix e fundador da
XenSource, anunciou em seu blog o XEN CLOUD PLATFORM
http://community.citrix.com/display/ocb/2009/08/31/The+Xen+Cloud+Project
O Xen Cloud Platform terá as mesmas funções disponibilizadas
no Citrix XenServer pois a Citrix esteja abriu o código fonte da
inteligência do XenServer.

5. XCP em poucas palavras
 Vertical stack for server
virtualization
 Distributed as a closed
appliance with CentOS 5.5
Dom0, misc DomU’s,
network & storage support
and Xen API
 Really: an open source
distribution of XenServer

12. Projeto Kronos
• Make the XAPI toolstack independent of CentOS 5.5
• Extend the delivery model
• Deliver Xen, XAPI and everything in between (storage
manager, network support, Ocaml libs, etc.) via your
favourite Linux distro
“apt-get install xapi” or “yum install xapi”
• The Plan:
• Initially Debian and Ubuntu (12.04)
• Later any major Linux distro (Fedora, etc.)

15. PARA ONDE ESTÁ INDO O XCP
www.centralcloud.info @lsantiagos

16. Para Onde Vamos
 XCP becomes XenServer “unstable”
(or the “Fedora of RHREL”)
 More experimental development such as project Kronos
 More flexibility for users of Xen
 Tracking unstable hypervisor/kernel
 More open development model
 XenAPI toolstack is more easily consumable
 Supporting the cloud and cloud projects
 Optimized for cloud use-cases
 Optimized for how usage patterns in cloud projects
