Xen Project Community Hosts Annual Developers Summit in August

We recently announced the program and speakers for our Xen Project Developer Summit happening in Toronto, Canada from August 25-26, 2016. The event will be co-located with LinuxCon North America.

The Xen Project hypervisor powers the new needs of computing and virtualization through a rich ecosystem of community members that focus on everything from security, embedded, and web-scale environments. The Summit is an opportunity for developers and software engineers to collaborate and discuss the latest advancements of Xen Project software, and better understand what’s next for Xen Project technology, virtualization and cloud computing.

In addition to presentations, we will be running a half-day hackathon alongside the Summit on the last day. Xen Project hackathons have evolved in format into a series of structured problem-solving sessions that scale up to 50 people.

This flagship event features presentations on the latest developments, best practices, collaboration, product roadmap updates and future planning from developers and users who are leading the way in server density, hardware, automotive, cloud and enterprise security.

This event is being sponsored by Citrix (Diamond sponsor), Huawei (Platinum sponsor) and Intel (Platinum sponsor). Please be sure to follow updates on the event via Xen Project’s Twitter, Google+ or Facebook page. Hashtag for the event is #xendevsummit.

We look forward to seeing you there!

Event Report: Xen Project Developer Summit 2015

This year’s Xen Project Developer Summit is over! We had two days packed with highly technical sessions that were attended by 120 delegates. Our sessions have – as always – been very interactive with lots of discussions during and after the talks. Of course we did also have lots of time for in-corridor conversations during breaks, which most of us look forward to every year.

Joint KVM and Xen Hackathon and Social Event

The joint activities between Xen and KVM have also been a great success, bringing developers from both communities more closely together. In particular the joint social event was a great success. I overheard many constructive conversations among members of both communities. In some cases, members of both communities were competing with each other in the bowling alley and playing pool: who said that a little bit of friendly competition can’t be fun (-: We will work with the organisers of KVM Forum such that we can build on this cooperation next year.

New Hyper Open Source Project Allows Developers To Leverage Docker and Xen Virtualization Infrastructure

Docker’s popularity and usefulness in cloud systems architectures is evident, having won over countless developers. Yet, it’s not a replacement for mature, proven and security-hardened virtualization technologies that support many of the world’s largest clouds in production.

So, while developers clearly want to take advantage of container technology to easily package applications, they also need a seamless migration path to their existing virtual infrastructure. That’s where our new partner Hyper announced today comes into play.

Hyper, a Chinese-based company with a new open source project by the same name, allows developers to run Docker images with Xen Project virtualization, version 4.5 or later. Download available here.

“Hyper offers the best of both worlds — VMs and containers,” said Xu Wang, Co-Founder at Hyper. “Our technology allows enterprises to leverage any mature, implemented virtualization infrastructure and eliminate unwanted complexity and also take advantage of container technology to easily package applications. We are partnering with Xen more closely to help developers get more out of their hypervisor, while also enjoying the benefits of container technology.”

To learn more, be sure to check out the presentation “Hyper: Make VM Run Like Containers” at Xen Project Developer Summit, Aug. 17-18. You’ll also find them at The Linux Foundation’s new ContainerCon event, as a bronze sponsor.

Hyper Enables the Next-Generation Container-as-a-Service

Caas (Container-as-a-Service) is gaining traction in cloud computing by leveraging the portability of Docker to avoid various technical limitations in a Platform-as-a-Service. However, the shared kernel approach introduces unnecessary complexity, overcapacity and security insecurity.

To eliminate these problems, Hyper uses virtualization to achieve hardware-enforced isolation. Unlike a VM + container approach, Hyper does not employ a GuestOS in the VM instance. Instead a HyperKernel, a customized Linux Kernel which includes Docker functionality, is loaded to host the Docker images. Hyper guests also does not require any Linux Container technology: in other words in Hyper guests do not require LXC, cgroups, namespace and  Docker daemon to run; they only require MOUNT namespace to support pods of Docker images.

Continuous innovation is the lifeblood of any project, and Xen Project is fortunate to have an extremely active and growing community. Partners like Hyper allow Xen Project to stay one step ahead of the industry with security, performance and scalability as cloud and computing infrastructures evolve.

2015 Xen Project Developer Summit Line-up Announced

I am pleased to announce the schedule for the Xen Project Developer Summit. The event will take place in Seattle on August 17-18, 2015.

The Xen Project Developer Summit brings together its community of developers and power users. Each year the event features the latest developments, best practices, collaboration, product roadmap updates and future planning from developers who are leading the way in server density, million-node data centers, automotive, mobile, graphic-intensive workloads, cloud and enterprise security.

For the first time, Xen Project Developer Summit and KVM Forum will co-host a Hackathon on Aug. 18 aimed at fostering technical collaboration between the two leading open source hypervisors in IT today. KVM and Xen users and developers will have the opportunity to collaborate and delve into work on libvirt code. A co-hosted evening event will be held that night.

Following is a sampling of confirmed speakers and presentations to be discussed in Seattle:

  • Dario Faggioli, senior software engineer, Citrix, and Meng Xu, PhD Student, University of Pennsylvania, will co-present the state of scheduling in Xen and the hypervisor provides a set of schedulers, each one suited for specific use cases.
  • Sainath Grandhi, Core OS engineer, Intel will present Xen containers to run Docker container applications sandboxed in a small VM as an alternative to bare-metal containers, providing tighter security and resource isolation.
  • Julien Grall, software engineer, Citrix, will target developers making a product based on Xen ARM requiring device assignment.
  • Juergen Gross, Linux kernel developer, SUSE, will outline suggestions for a systems architecture that is much more fault tolerant against hardware and software failures.

  • Liu Jinsong, PM and RAS maintainer, Alibaba, will introduce live migration at AliCloud, summarizing the technical virtualization, network, and storage problems that need to be solved to make live migration work at AliCloud.
  • Mark Kraeling, product manager, GE Transportation, will talk about virtualizing the locomotive and how GE uses about how GE uses Xen for x86-based processors, and KVM for ARM-based processors.
  • Tamas Lengyel, security researcher at Novetta, University of Connecticut PhD student, will shed more light on current trends in virtualization security, pitfalls and new features coming in 4.6.
  • Wei Liu, Xen 4.6 release manager, Citrix, will give a status report on the upcoming Xen Project 4.6 release.
    Stefano Stabellini, senior principle software engineer, Citrix, will explain how to deploy OpenStack using the Xen Project hypervisor to run your VMs.
  • Zhi Wang, engineer, Intel, will provide a detailed update on the evolution of Intel Graphics Virtualization Technology for full GPU virtualization.
  • Konrad Wilk, software director, Oracle, will discuss the design and functionality of xSplice, which offers a method for live patching without requiring a system to reboot.
  • Marc Zyngier, kernel hacker, ARM, will share a hypervisor agnostic view of virtualization extensions added to the latest ARM architecture.

Birds of a Feather session and Discussions

Besides presentations, the developer summit will also provide an opportunity for in-depth interactive discussions (Birds of a Feather sessions), which allow deep interaction and collaboration between Xen Project developers and community members. These will happen in a second track alongside part of the main event.

A Tale of Two Amazing Open Source Hypervisors

Born in the logic of ones and zeroes and forged in the heat of battle, two hypervisors–sworn foes in the realm of virtualization–are about to unite in a way many never thought possible. Over beer and code.

Join the teams behind Xen Project Developer Summit and KVM Forum in Seattle as they co-host a social event that will rock the virtualization world. On August 18, 2015, at the close of the Xen Project Developer Summit and on the eve of KVM Forum, attendees of both events can come together and collaborate in the best way possible: with crudites and hors d’oeuvres (and beer).

Virtualization is one of the most important technologies in IT today, so it makes perfect sense for the two best hypervisor projects to collaborate and socialize at an event that celebrates their similarities and bridges that gap between all things KVM and Xen.

virtlogos

The party will get started Tuesday, August 18, at a time and location to be announced shortly! Attendees of both conferences are welcome to come and join the fun and be reminded of what open source is all about.

And before raising a pint to toast to friends both old and new, there’ll be an opportunity for some serious coding. So, if you’re a KVM contributor, a Xen zealot, or a power user of XenServer or oVirt, the joint KVM Forum and Xen Project Developer Summit Hackaton is the place to be during daylight hours.

The hackathon will be held on Tuesday, August 18, 2015, in the Virginia Room, 4th Floor, Union St. Tower of the Sheraton Seattle from 1:00pm to 5:00pm. Aiming to foster technical collaboration between the two best hypervisors in IT today, the event will enable participants to learn more about what makes each project work, as well as to delve into work on libvirt code that could bridge the gaps between Xen and KVM. Bring your laptops, your ideas, and your code and help improve open source virtualization for the good of both projects. Collaboration is what makes open source truly great, so come be a part of greatness.

Finally, we all know greatness is nothing to be shy about, so we encourage Xen ecosystem developers, contributors and users to submit a speaking proposal for Xen Project Developer Summit.  The CFP is open through May 1. The topics of discussion are nearly endless — from scaling and optimizations, nested virtualization, performance enhancements, and hardening and security to high availability and continuous backup desktop virtualization, new devices, boards and architectures and more. Presenting at #xendevsummit is the excellent way to share your knowledge of all things Xen and help define and plan for the future of Xen. If you’re still looking for inspiration, check out last year’s slides and topics. Register soon to benefit from early bird pricing. See you in Seattle!
