Thanks to Zoltan Herpai for doing the massive processing job to convert all the recent Xen Summit Asia 2009 high definition videos to YouTube for easier viewing. You can find the entire conference video set at http://www.youtube.com/wigyori#p/u.
In January 2009, I posted my goals as your community manager for 2009 â€“ http://blog.xenproject.org/index.php/2009/01/02/community-manager-goals-for-2009/. My focus was on three main areas:
- Xen Summits and Events
As we end 2009, I would like to highlight some of the community achievements around those three goals:
- Xen support is now available in English on the main Xen.org mailings lists, Portuguese from the Xen Brazil User Group, Italian from the Xen Italy User Group, and Japanese on email@example.com. Xen support is also available on IRC at Freenode:##xen and a new trial online discussion forum.
- Xen promotional materials are available in English, Portuguese, Chinese, Japanese, German, and Spanish.
- The Xen.org wiki is currently available in English, Spanish, German, French, Chinese, Japanese, Korean, Russian, and Italian
- Events for Xen.org held in United States, Brazil, Chile, China, & Germany
- Expansion of the Xen Advisory Board to include Oracle, Fujitsu, & VA Linux Systems Japan.
- Tremendous growth, over 60%, in the many social networking groups for Xen.org at Facebook, LinkedIn, Ohloh, Xing, and Linux.com.
- 20+ independent community projects based on/for Xen currently tracked on Xen.org
- User Groups â€“ Brazilian Xen User Group and Italian Xen User Group firmly established and growing
Xen Summit and Events
- Xen Summit North America at Oracle (Feb 2009)
- Xen Directions Europe at LinuxTAG (June 2009)
- Xen.org Booth at CloudWorld 2009 (August 2009)
- Xen.org Presentation at Latinoware 2009 in Brazil (Oct 2009)
- Xen Summit Asia at Intel (Nov 2009)
- Xen Presentation at Jornadas Regionales de Software Libre in Chile (Oct 2009) : Community Member
I want to thank everyone in the community for their incredible efforts in 2009 to help make Xen.org a leading open source project. I will be publishing my new community goals for 2010 at the start of January and look forward to another challenging year in supporting the work of the Xen.org community.

2010 Prediction: IT gets smart about server virtualization and focuses on desktop virtualization, virtual networking and virtual appliances
I’m returning from a trip to Cambridge-the home of the Citrix Xen development team who maintain Xen.org and our contributions to the Xen Client Initiative and Xen Client Platform, and who also produce Citrix XenServer and XenClient.Â Spending time with one of the world’s best technical engineering teams is an incredible privilege and I treasure every moment, such as seeing first-hand the latest developments and results from our comparative performance tests.
As I write this, the Copenhagen Climate Conference is approaching crunch time. While the diplomats tussle over abstract, “squishy” targets, I have been fortunate to be able to acknowledge the tremendous contribution that our team, together with the Xen community, has made to the industry and our planet.
In 2009, XenServer helped to reduce CO2 output by an estimated 5 million tons, and when you include the footprint of all Xen variants, including EC2, Rackspace, SoftLayer and other large Xen clouds, I think it is fair to say that the Xen community has delivered a greater contribution to reductions in CO2 than any other open source project, and a greater contribution per developer than any other software product.Â We all owe the Xen community a debt of thanks. And as importantly, we owe future generations a duty of care in how we develop our IT environments.Â So let’s start 2010 with a resolution to virtualize every server.Â Keep track of your own carbon footprint and see what a difference you can make.Â The average American generates about 20 metric tons of CO2 per year.Â According to VMware, each server you run generates about 4. When you virtualize your next server with (free) XenServer, and run 10 VMs, you will save 40 tons-giving you a net carbon footprint of-20 tons. A great contribution.
My predictions for 2010?
Will this be the year that VMware customers finally realize that they are paying twice for the benefits of Moore’s Law (once for the server and once for the hypervisor that lets them use it)? Certainly more than a few have made the switch to Xen or Hyper-V, and I predict very substantial growth next year.Â XenServer will finish 2009 having added about 35,000 customers.Â I’ll go out on a limb, and predict that we’ll double that number in 2010. Having seen what’s cooking in Cambridge, I can also predict with absolute confidence that independent benchmarks will show that XenServer beats every other hypervisor in performance and scalability, for all workloads.
2010 will be a year of real change in virtual networking.Â Cisco, whose innovative Nexus 1000V virtual switch for VMware relies on its VN-Tag and VN-Link protocols, will find itself having to adopt the IEEE 802 standard protocols for Virtualized Ethernet Bridging, which have developed based on a counter proposal from HP and others. Virtual switching will dramatically change the way that enterprises manage their virtual environments, simplifying network configuration and reducing errors.Â At the same time, virtual switching will challenge the virtual appliance vendors that have hitherto managed to snoop traffic on the hypervisor by connecting to a promiscuous port on the software bridge in the hypervisor.
Further challenges for the virtual appliance vendors will come as SR-IOV hardware I/O virtualization goes mainstream in the later part of 2010. Suddenly it will be possible to plug a virtualization-safe NIC into a VM, meaning that VMs become hardware specific once again, and that all packets leave the server. “Bump in the Wire” virtual appliance vendors that do not have a good strategy in the area of virtual switching, will fall by the wayside.
Getting out of the virtual infrastructure tussle, I predict an extremely rapid ramp in the virtual desktop market.Â I suspect that the Windows 7 upgrade cycle (and the disappearance of support for Windows XP in 2011) will be one of the key motivators. Now is the time to upgrade your users to Windows 7. It’s smaller, zippier and offers great app compatibility. It’s also fully supported on XenServer now. So rather than having to deploy Windows 7 on all those legacy PCs, you can deliver it as a service using XenDesktop 4 with HDX- without having to go near the desktop hardware.
It will be interesting to chart the development of Google’s Chromium OS, now with a built-in KVM style hypervisor. It’s probably safe to predict that Chromium based desktop appliances will appear in the not too distant future, driving the cost of tethered user devices downward. But Chromium faces its own challenges-not the least of which is the notion that every app be browser based. It will take time to deliver a comprehensive application suite and so adoption will be slower than many might like to predict.
It is with great pleasure that I announce that now that the multiboot patch got commited in Xen’s unstable tree for the coming 4.0 release, I have merged GNU Mach’s Xen tree into master, i.e. although it has already been used for the Debian buildds for a couple of years already,
GNU Mach now officially has Xen domU support!
(yes, GNU Mach, not Hurd, as no change was needed in the Hurd part 😀 )
Updated builds are available as usual on
