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.

Xen Project Starts the New Year with a Bang!

January Features Major Xen Project Activities at Two of the Biggest FOSS Conferences of the Year!

The Xen Project is starting 2016 on a high note by sponsoring major events at both the largest community-run FOSS conference in North America (SCALE) and the world (FOSDEM). In addition to a flurry of technical talks in the main program of each conference, Xen Project is organizing additional co-located events.

Unikernels and More: Cloud Innovators Forum (CIF16) Comes to Southern California Linux Expo (SCALE)

Xen Project is proud to announce the world’s most wide-ranging Unikernel user event ever held! We have a full day of talks which cover everything from the basics of Unikernels to building Unikernels to reworking the cloud to adapt to the realities of Unikernels. We have speakers from some of the biggest research companies (like IBM, NEC, and Ericsson) as well as some of the most leading edge organizations. Just take a look at the talk lineup:

To join us, simply register at the SCALE 14x website.

And all this is in addition to a couple Xen Project talks in the SCALE program itself:

Xen Project talks at FOSDEM

As in past years, the Xen Project will have a booth and demos at FOSDEM and is well represented at FOSDEM Devrooms.

To join us, simply attend FOSDEM (no registration required) and enjoy the talks.

Xen Project @ FOSDEM

Going to FOSDEM’15? Well, you want to check out the schedule of the Virtualization & IaaS devroom then, and make sure you do not miss the talks about Xen.

Here they are the talks, in some more details:

Last but certainly not least, there will be a Xen-Project booth, where you can meet members of the Xen community as well as enjoying some demos.

The booth will be in building K, on level 1.

We also have a handy guide available, that you may want to print out before going to the event.

The Xen of Static Checking, Part 1: bug-free code without the effort

OK, maybe the title of this post is a slight exaggeration but it’s good to have goals for the future!

It’s a goal which many would argue will be unreachable without the genesis of Strong AI. It’s also a goal where we can achieve very useful results just by trying to get there. I’m going to write a series of articles about my current work on static checking the Xen codebase. The goal here is to find errors before they occur, spot bugs that aren’t caught by human reviewers and improve the overall quality of codebase. Unfortunately, global harmony and toast which doesn’t fall butter-side-down are probably still outside the scope of this work – sorry.

This first article gives an overview of the historical background of static code checking. Future articles in this series will describe what I’m doing to apply static checking to the Xen codebase and the possibilities for Xen in the future.
