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
9. Próximos lançamentos XCP
XCP 1.1 (released)
Mostly bug fixes since XCP 1.0
Next major release scheduled for Q3’2012
Tentatively named XCP 1.5
Will have Xen 4.1, Linux 2.6.32
New features: Disaster Recovery, GPU passthrough, 1TB
host memory
New guest support: Solaris, Ubuntu 10.10, RHEL 6.0
10. 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.)
11. 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)
12. Project Kronos : Next Steps
Milestone 1
First release to coincide with Ubuntu 11.10
Published as Ubuntu and Debian apt repo
Milestone 2
Second release to coincide with Ubuntu 12.04 LTS
Will be in Debian unstable and Ubuntu repos
Follow along with development

15. 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
16. 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
