The document discusses Xen Cloud Platform (XCP), an open-source virtualization platform. It notes that XCP was originally developed at the University of Cambridge and was later acquired by Citrix. It provides an overview of XCP's capabilities, including running multiple operating systems simultaneously on the same hardware. It also discusses XCP's use in cloud computing projects and upcoming releases that will include support for newer operating systems and features like GPU passthrough and increased memory support.

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 Cloud Xen Project terá as mesmas funções disponibilizada 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

 OpenNebula
(XCP 1.0)
 CloudStack
(XCP 1.0 & 1.1)
 OpenStack

11. 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.)
www.centralcloud.info @lsantiagos

12. Projeto Kronos
Why are we doing this?
•More easily consumable
•This is what cloud orchestration projects prefer
• Pick your OS
• Pick the hypervisor
• Pick the cloud orchestration stack

Because it's the right thing to do (and because it's just really
cool)

17. 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
www.centralcloud.info @lsantiagos

18. Visão XCP

XCP is the configuration of choice for clouds

XCP bridges the gap between Open Source Xen and
XenServer / XCP communities

XCP becomes the Xen Community Platform
