Monthly Archives: May 2009 & Social Networks

I have created yet another group in the newly launched site –  That brings to 6 the number of Social Network sites that have groups; that I am aware of. If you know of others please let me know. (Note – SlideShare is not considered for this blog post)

This brings me to today’s blog post – what are we doing with all these social networks? I am currently monitoring and adding information to the following groups:

So, who is in these groups? Based on the survey data that I am now compiling, it appears that our community is not really involved in these sites (N=69).  I have been posting weekly community updates in these groups as well as having this blog directly feed the sites to ensure that the latest info is available. Other than that, I am not really sure what people are looking for on these sites? If you were one of the people who answered below – please let me know what you use these tools for? I want to ensure that I supply the information these groups are looking for and I am currently unsure.

Are you coming to Xen Directions Europe 2009?

Xen Directions Europe 2009 is the first “techno-marketing” event for presenting the Xen hypervisor and the products/solutions based on it as well as give university researchers a chance to show how Xen is being leveraged. This event is being co-located at the LinuxTAG conference in Berlin, Germany on June 27, 2009. All LinuxTAG attendees can participate in the Xen Directions event and people interested in just Xen Directions can register for a single day LinuxTAG pass which I believe is about 10 euros.

The agenda for Xen Directions is a nice mix of enterprise companies, university researchers, smaller companies, and “staff”. The global nature of our community is also on display with speakers from South America, Europe, and North America.

Speaker                   Company/University
Ian Pratt         
Jerg Theurer           HP
Dirk Hohndel          Intel
Ruben Montero     University of Madrid
Christian Rothe     Oracle
Frank Kohler          Citrix Systems
Boris Quiroz            Substance
Bjorn Brundert      Lufthansa Systems
Chris Schlaeger     AMD
Stephen Spector

The complete agenda with topic information is available in English and German.

Additionally, the next Xen Summit event for the development community is scheduled for November 19-20, 2009 in Shanghai, China at Intel’s R&D facility. More information on this event will be made available later this summer.

Xen 3.4 Launch Announcement is pleased to announce the latest release of the Xen hypervisor, the open source industry standard for virtualization. is a global community of independent and industry developers, university researchers, users, and virtualization gurus who regularly contribute to the shared design, development, support, and improvement of the Xen hypervisor platform.

The new release, Xen 3.4, furthers the vision of creating a powerful, efficient, and ubiquitous virtualization hypervisor. As part of the Xen community’s commitment to continuous improvement, the new hypervisor offers significant enhancements in the following areas:

•    Xen Client Initiative (XCI) Enhancements – continues develop industry virtualization standards for desktop and client devices. Xen 3.4 contains the initial XCI code release providing a base client hypervisor for the community to extend and improve. This new version of the Xen hypervisor expands the hardware options for the leading open source virtualization platform.

•    Reliability – Availability – Serviceability (RAS) – In addition, Xen now delivers a collection of features designed to avoid and detect system failures, provide maximum uptime by isolating system faults, and provide system failure notices to administrators to properly service the hardware/software. The combination of these services provide for a robust Xen hypervisor with fault-tolerant and back-up capabilities built-in.

•    Power Management – Xen 3.4 improves the power saving features with a host of new algorithms to better manage the processor including schedulers and timers optimized for peak power savings.

Xen 3.4 is currently available via free download to developers by visiting the website at:

Momentum in the Xen Community

The Xen community remains strong and active.  On average, receives more than 750 new code submissions to the source tree each month from developers across the world working on an array of solutions within the hypervisor. Industry leading companies such as Intel, AMD, HP, IBM, Oracle, Red Hat, Sun, Fujitsu, and Novell are part of the vibrant community and contribute to the development of the hypervisor code. The Yankee Group’s Third Annual Virtualization Survey reports a significant increase of commercial Xen-based solutions which represent 17 percent of total market share. This includes a Citrix XenServer share of 11 percent, plus an additional six percent from other open source suppliers.

On an ongoing basis, university research and other high profile Xen projects   are regularly incorporated or run on the hypervisor. For example, Project Snowflock from the University of Toronto leverages the Xen hypervisor to instantaneously launch thousands of virtual machines for fast, efficient, scalable parallel processing and Project HXen extends the Type1 virtual machine monitor (VMM) functionality in Xen to a Type 2 VMM for a simplified method of deploying Xen to desktops, laptops, USB sticks and other devices where the base OS is left in place. For high availability, Project Kemari  and Project Remus provide transparent, comprehensive, high availability to ordinary virtual machines running on the Xen virtual machine monitor by maintaining a completely up-to-date copy of a running VM on a backup server, which automatically activates if the primary server fails. These are examples of the various contributions across academia and within the development community to

To date, thousands of companies and universities have chosen the power of open source Xen, making the Xen hypervisor their choice to provide virtualization in their IT environment. Last month, more than 100 attendees from the open source community participated in the Xen Summit sponsored by Oracle; similar events are planned in Europe and Asia this year to support the growing global community.

In addition, the community is committed to providing more resources to its members:

• Solutions Search is a new online tool enabling customers to quickly find consultants, hosting providers, developers, and solutions built on the Xen hypervisor platform. This search system profiles the growing ecosystem for the Xen hypervisor.

• is committing resources to expand the global footprint for support and promotion of the open source Xen hypervisor. Materials are being translated into Spanish, German, Portuguese, Chinese, and Japanese with the community Wiki now available in English, Spanish, French, Russian, German, Chinese, Korean Japanese, and Italian. Support groups for customers are also available in English, Portuguese, Japanese, and Italian.

•    Finally, is excited to offer an event for virtualization customers and prospects in Europe called Xen Directions, being held in conjunction with LinuxTAG on June 27, 2009 in Berlin, Germany.  A variety of hands-on Xen demonstrations will be offered to the European technical audience for the first time. In 2010, will be hosting the first event in South America as part of the FISL event in Brazil.
