It truly was an amazing year for Xen.org! The key highlights included Dom0 supporting going into mainline Linux kernel, Project Kronos, and renewed focus Â Xen for ARM. All three of these projects are examples of standing on the shoulders of giants.
- In 2007, Jeremy Fitzhardinge announced the plan to Xen domU (guest) support in Linux upstream (via pv_ops) with domU support landing in Linux 2.6.23. Every Xen Summit since then had pv_ops updates of some kind and at Xen Summit North America 2011 Konrad described how Linux 3.0 was the first usable Dom0 kernel. (See Konrad’s blog post that details how we got there).
- In 2006, Ewan Mellor sent out a draft specification for the Xen API (XAPI). In 2009, The Xen Cloud Platform was announced and XAPI was released as open source. In 2011 XCP 1.0 and XCP 1.1 were released, Project Kronos was announced, and initial XAPI packages are now available in Debian.
- In 2007, Sang-bum Suh described Samsung’s port of Xen to ARM. In 2011, Stefano Stabellini announced the ï»¿Xen port to Cortex-A15 / ARMv7.
In 2011, Xen.org welcomed Lars Kurth as our community manager. Lars’ impact can be seen most notably in a formalized governance model, a new Xen wiki, and numerous events that Xen.org held and attended (described below).
- In 2011,Â Xen 4.1 was released (4.1.1 and 4.1.2 as well).Â In addition to working with upstream Linux, the Xen team also worked with upstream QEMU to getÂ Xen support in QEMU.
- Other XCP Highlights included Â development moved to github,Â OpenStack Support, CloudStack Support, and OpenNebula Support.
- 2011 was the year of the first two Xen Hackathons:Â Xen Hackathon Cambridge andÂ Xen Hackathon Munich.
- We had five students work on Google Summer of Code projects.
