Recap of LinuxCon China and Xen Project’s Growth in the Region

It’s been a very busy month or so for the Xen Project. During mid-June, I was lucky to attend and speak at LinuxCon + ContainerCon China held in Beijing. There I spoke on the topic of securing embedded systems with the hypervisor and live patching, virtual machine introspection and vulnerability management alongside my colleague Cheng Zhang of Citrix.

Open source has grown tremendously in China over the last few years, with Xen Project technology being a key enabler for cloud computing. Most recently, the Xen Project announced Huawei joining the Project’s advisory board. Huawei is one of a growing number of Chinese companies leveraging and contributing to the Xen Project’s software. Other organizations include Alibaba, Fujitsu (China), Intel (China), Tencent, Inspur, and more.

The Xen Project hypervisor currently powers Alibaba Cloud, which is growing at a massive rate with incredible potential.

Many ask why is this growth happening in China and why now? There are many different reasons, but I think the main point is: As key technologies are increasingly built collaboratively, more and more Chinese companies are using open source to leapfrog competitors. By joining Linux Foundation projects, in-country organizations are helping to drive further growth and development.

Collaboration in China and at the Conference

Contributions with the Xen Project have greatly expanded over the last few years, especially in contributions and membership coming from China. In our latest release, Xen Project 4.9, we had 25% more contributors to the core hypervisor, and an increase of 17% of contributions coming from the hypervisor, tests, and other components. We received several contributions from individuals based in China as well as Fujitsu (China), Huawei Technologies, and Intel (China).

We are generally seeing more companies (in China and beyond) participating in the project with an eye toward automotive, embedded, security, and native-cloud computing.

During the conference, I was able to meet up with community members from Alibaba, Huawei, Hyper_, Intel and others.. Key highlights and conversations for me included:

  • In the last year, we have seen very rapid adoption of Xen Project based products in government (e.g. China State Grid), industry (e.g. CTCI), telecoms (e.g. China Mobile), banking/financial (e.g. ICBC, People’s Insurance Company of China) and are starting to see adoption in High Performance Computing. One surprising factor that is leading to rapid adoption of open source in China is that many industries are required to perform code audits on software with the aim of strengthening cybersecurity, which gives open source software a significant edge.
  • I had lots of discussions on the “ins and outs” of Virtual Machine Introspection, after I highlighted that VMI defeated WannaCry/EternalBlue a priori mentioned in my live patching, virtual machine introspection and vulnerability management talk. As I learned most WannaCry victims were based in China including a number of companies such as the China National Petroleum Corporation, which led to 20% of petrol stations across the mainland going offline.
  • Live Patching, and its potential limitations and the complexities of how to build and validate them, were also high on the list of discussions which came up several times.
  • Another highlight was a discussion around the proposed Shared coprocessor framework for Xen, whose design is currently being finalized and will support sharing of GPUs, DSPs, FPGs and security once the prototype has been completed and upstreamed. I had originally assumed that co-processor sharing was mainly of interested either in embedded or for niche cloud use-cases, but was surprised to learn that there may be much more market pull than anticipated.

I’m looking forward for continued collaboration and innovation in this region.

FOSDEM Here We Come!

It’s that time of the year again – FOSDEM is coming to Brussels February 4 – 5 and the Xen Project team will be attending again.

We’ll be at a booth with Citrix, Oracle, both Xen Project members, and Vates. Xen Orchestra, which offers a complete web UI for controlling a XenServer and Xen infrastructure, will be demoed at the booth. You can find us in section K, level 1, group C, booth 5 or to make it easier between TOR/TAILS and OpenStack.

If you want to learn more about Xen Project technology, FOSS licenses and unikernels, then we recommend you come by the booth and/or head to the following presentations:

Live patching the Xen Project hypervisor
*Happening Saturday from 11:30 – 11:55
Live patching is the process of updating software while it is running, i.e. no more reboots. This type of technology is particularly important for cloud providers who need to keep themselves up and running 24/7. This talk covers everything from the design and implementation of live patching for Xen Project software to how it differs from live patching for Linux.

Mixed License FOSS Projects
*Happening Saturday from 11:35 – 12:20
Many projects start out with the intention of staying a single license FOSS project, but as your project grows there are some different licenses that you may not have anticipated. This talk will explore unintended consequences, risks and best practices through Xen Project examples on license issues. If you are an open source project that is growing fast, this is definitely a talk you don’t want to miss.

Adventures in Building Unikernel Clouds
*Happening Saturday from 14:45 to 15:25
Unikernels are a great approach to building the next generation of cloud infrastructure – they are performant and have a small attack surface. Even though the concept of a unikernel is not new, there has not been a ton of work done in building them for the infrastructure today. This talk provides a deep dive into the various layers of infrastructure that one needs to build out their own infrastructure of unikernels.

Towards a HVM-like Dom0 for Xen: Reducing the OS burden while taking advantage of new hardware features
*Happening Saturday from 18:45 to 19:00
Xen Project hypervisor uses a microkernel design that allows multiple concurrent operating systems to run on the same hardware. One of the key features of Xen Project software is that it is OS agnostic, meaning that any OS (with proper support) can be used as a host. This talk provides an overview on the different kind of guests supported by Xen Project software and how these new hardware features are used in order to improve and evolve them. It also describes the design and implementation of a new guest type, called PVHv2, and how it can be used as a control domain (Dom0).

We look forward to seeing you there. For those who can’t attend, follow our Twitter feed for FOSDEM updates and to stay up-to-date  on what’s happening with the project.
