The O’Reilly Open Source Convention (OSCON) is one of the biggest open source conventions in the World, bringing together open source projects, developers, users and companies. Xen.org, the home of the open source Xen Hypervisor, was at OSCON this year promoting the Xen hypervisor and its open source community.
Xen Fu Panda rocks at OSCON!
OSCON was a great way to connect to many users we did not know about. We were amazed about the number of people that are using open source Xen or one of its commercial distributions and told us how great and flexible the product is. We also learned about many innovative and unusal use-cases of Xen technology. I was surprised about the use of the Xen hypervisor in software development to run virtualized test labs and software production environments. Some users are stretching Xen to the limit running 50+ virtual machines on a single small server.
The key lesson we took away from OSCON is that Xen has a large but largely silent user base, which deserves more focus by Xen.org and is willing to share their stories. Another lesson is that our developer community is moving in the right direction: Xen being available in Linux 3 and project Kronos is exactly what our open source users need, want and get excited about. These efforts are complemented by commercial projects such as Citrix’ project Olympus as explained in a Citrix /Rackspace talk called Achieving Hybrid Cloud Mobility with OpenStack and XCP.
Xen Summit, Aug 2-3
Many of the themes we touched upon at OSCON and in this blog post will be explored in much more detail at XenSummit, Aug 2-3. We will hear Xen user stories from Amazon Web Services, Globo.com and case studies on Xen memory sharing and swapping from HUAWEI. Of course there will also be Xen project updates and an overview of the Linux 3 work performed by our community and an outlook on what will happen next. Other areas that will be covered include talks on Xen and Openstack, including a talk by Gluster, updates on Xen based research and talks on Xen in the embedded space using the ARM as well Intel architectures. The event is fully booked, but Xen.org will be publishing the talks and recordings after XenSummit. Xen.org will also be at the Silicon Valley Linux User Group meeting, the evening of Aug 3rd.
