Last month, the Xen Project community gathered, virtually, to collaborate, connect, and solve the important challenges we all face. While our gathering may have looked different than in years past, we made the most of it and heard from a broad set of community members both in presentations and in collaborative Design Sessions.
A few highlights:
- Xen Weather Report: A look back over the last year including two major releases, Functional Safety SIG, and of course, the incredible impact of Lars Kurth, community manager of the Xen Project who suddenly passed away in January of 2020.
- Xen Cache Coloring: Interference-free Real-time Virtualization, Stefano Stabellini, Xilinx: Cache Coloring is a new feature for Xen to better support real-time workflows.
- Xen PV Block in U-Boot – Anastasiia Lukianenko: In this talk, Anastasiia, who works at EPAM, explains the benefits of having generic guest bootloader in embedded systems
- Reference Counting in Xen: An Introduction – George Dunlap, Citrix: Xen reference counting is a core, unique part of Xen. This talk will start at the beginning, presenting the basic concepts behind reference counting, and slowly building up the special cases and the purposes behind them.
- Arm Contributions to Xen Based Safety Systems – Bertrand Marquis, Arm Ltd: This talk describes the autonomy stack, a Yocto based collection of layers providing a way to create a Xen based virtualized autonomous system.
- Running Xen without the Direct Map – Hongyan Xia & David Woodhouse, Amazon: The Xen Summit last year proposed Secret-Free hypervisor and provided a roadmap for the goal. This talk highlights how one of the two major goals, direct map removal, has been achieved in Xen.
Thank you to all who attended and participated. We look forward to gathering in person when it is safe to do so.
