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.

A Recap of the Xen Project Developer Summit 2016

The Xen Project descended on Toronto, Canada in late August for its annual Xen Project Developer Summit. The Summit is an opportunity for developers and software engineers to collaborate and discuss the latest advancements of the Xen Project software. It also gives developers a chance to better understand new trends and deployments in the community and from power enterprise users.

From community growth to new emerging use cases, the Summit covered a lot of ground. Developments within core technologies such as security, graphics support and hardware support were discussed. We also covered emerging technologies such as automotive, embedded and IoT. All sessions were recorded and are available here and also on slideshare (follow this link for summit presentations).

Below is a summary of a few videos that feature technology that has been recently introduced into the Xen Project hypervisor as well as emerging technologies that are being built with Xen Project technology.

New Feature Technologies from Xen Project Community and Power Users

In Xen Project 4.7, we introduced Live Patching as a technology preview. Live Patching gives system administrators and DevOps practitioners the ability to update the Xen Project hypervisor without the need for a reboot. Konrad Wilk, software development manager of Oracle and Ross Lagerwall, software enggineer at Citrix, provide insight into how it works, what the difficulties were to implement, and how it compares to other technologies for patching (kGraft, kPatch, kSplice, Linux hot-patching).



Dimitri Stilliadis, CEO of Aporeto, provides a great overview of the benefits of using Xen Project software to provide an execution environment for Docker apps. This approach allows VM-like isolations for security measures without having to sacrifice performance. The presentation introduces a new paravirtualized protocol to virtualise IP sockets and provides the design and implementation details.


Data breaches are happening all the time, and there are many ways that organisations are trying to stop this through detection, pattern matching and behavioural analysis. However, Neil Sikka, founder and CEO of A1LOGIC, provides a new way of looking at this problem and solving this problem by using the Xen Project hypervisor to enforce data loss prevention. It doesn’t use any type of detection, heuristics, pattern matching or behavioural analysis, but rather a strictly algorithmic approach rooted in hardware.

Embedded Projects and Xen Project Software

Members from the Xen Project sister community OpenXT, an open-source development toolkit for hardware-assisted security research and appliance integration, were present to provide some insights into how Xen Project is working within the embedded space and best practices for embedding Xen Project on mobile and tablet devices.

If this is an area that you are interested in, check out Christopher Clark (consultant and interoperability architect at BAE Systems) overview of the OpenXT Project, which has begun to attract new users and contributors. We also recommend Chris Patterson’s and Kyle Temkin’s step-by-step guide on the challenges and lessons to get Xen Project software started on phones and tablets. Chris is a advising computer engineer for AIS and Kyle is researcher for AIS.


Emerging Technologies

Xen Project is consistently becoming more common within automotive and aviation. Xen Project 4.7 introduced the ability to remove core Xen Hypervisor features at compile time via KCONFIG. This allows a more lightweight hypervisor, which is perfect for IoT scenarios and better for security-first environments, like automotive.

Sangyun Lee, senior embedded software engineer of LG Electronics, presents on the real-time GPU scheduling of XenGT in Automotive Embedded systems. It introduces the real-time GPU schedule of XenGT running on automotive embedded systems and explains why this should be used for an automotive system.


Xen Project is consistently being used within embedded systems for automotive. Earlier this year at CES, GlobalLogic showcased its technology behind Nautilus, which is the company’s virtualisation solution that enables multiple domains to share the GPU hardware with no more than a 5 percent overall in performance changes. More on this technology and how it uses Xen Project here.

The summit was a huge success with many interesting conversations. The Xen Project thanks everyone who attended and presented as well as the sponsors of the event Citrix, Huawei and Intel.

Don’t Miss Xen Project & KVM Joint Reception at LinuxCon

Last year, we really enjoyed co-hosting a hackathon and social event with the KVM community. It spurred really interesting conversations, a bit of friendly competition and some community bonding.

Back by popular demand is another joint KVM community event. Xen Project and KVM are hosting the joint social event at the Hockey Hall of Fame (this is Canada after all) on August 25th during the Xen Project Developer Summit and KVM Forum. The event will be held from 7:00pm to 11:00pm.

xenparty2This will be a great evening for anyone who is attending the Xen Project Developer Summit and KVM Forum, August 25 – 26.

xenparty

The Hockey Hall of Fame is a ten minute walk from the Westin where LinuxCon and ContainerCon are taking place. There will be plenty of shop talk of course. The Xen Project is increasingly more popular in IoT, automobile and embedded use cases, and a staple open source software in many of the largest companies today.

But there will also be plenty of time to check out the interactive hockey games, amazing hockey memorabilia, food, and drinks. Your badge is required to enter the party.

If you are interested in joining us for the Xen Project and KVM party, you must be attending one of these events. If you haven’t already, registration for the Xen Project Developer Summit is here. A few more highlights include:
