Xen Project Announces Schedule for its Annual Developer and Design Summit

Today, we are excited to announce the program and speakers for the Xen Project Developer and Design Summit. The summit brings together developers, engineers, and Xen Project power users for in-person collaboration and educational presentations. The event will take place in Nanjing Jiangning, China from June 20 -22, 2018.

This is the fifth annual Xen Project Summit with presentations and panels focusing on hypervisor performance and development, security, automotive and much more. The conference will kick-off with a weather report from Lars Kurth, chairperson of the Xen Project and director of open source at Citrix.

At last year’s Xen Project Developer Summit in Budapest, Hungary.

A sample of presentations include:

  • Sung-Min Lee, principal engineer at Samsung Electronics, will present a production-ready automotive virtualization solution with Xen.
  • Marek Marczykowski-Górecki, senior systems developer, Invisible Things Lab, will present on linux-based device model stubdomains in Qubes OS.
  • Julien Grall, senior software virtualization engineer at Arm, will share capabilities that were added to the latest revision of the ARmv7-A architectures and how Arm has been improving virtualization support with incremental versions of the Armv8 architecture.
  • Felipe Huici, chief researcher at NEC, and Florian Schmidt, research scientist at NEC, will co-present on Unikraft, a sub-project of the Xen Project aimed at automativing the process of building customized unikernels tailored to a specific applications.
  • Bo Zhang, business analyst at Huawei, will introduce Huawei Cloud’s optimization on the Xen platform to solve regular problems that occur in customer scenarios

You can view the full schedule here.

Beyond panels and presentations, the Xen Project will be running design sessions that share a similar format to Xen Project hackathons. Attendees of the conference have the opportunity to propose design sessions during the conference. Current design topics already include Making Safety Certifications for Xen Easier, From Hobbyist to Maintainer: Why and How and Reworking x86 in Xen (Current and Future Plans).

If you’ve never attended a Xen Project Developer and Design Summit, check out last year’s presentations to get a better feel for the event.

A special thank you Citrix for being a diamond sponsor of the summit.

 

Xen Project 4.10.1 Available

I am pleased to announce the release of 4.10.1. Xen Project Maintenance releases are released in line with our Maintenance Release Policy. We recommend that all users of the 4.10 stable series update to the latest point release.

These releases are available from their git repositories

xenbits.xen.org/gitweb/?p=xen.git;a=shortlog;h=refs/heads/stable-4.10 (tag RELEASE-4.10.1)

or from the XenProject download page

www.xenproject.org/downloads/xen-archives/xen-project-410-series/xen-4101.html

These releases contain many bug fixes and improvements. For a complete list of changes, please check the lists of changes on the download pages.

Summer = Xen Project Internships!

We received a lot of amazing submissions for our summer Outreachy internship program and have accepted Dafna Hirschfeld to join us in creating new execution targets for Unikraft. Unikraft is a Xen Project incubation project that aims to simplify the process of building unikernels through a unified and customizable code base.

Currently, Unikraft supports building images that can be executed as a virtual machine on Xen and KVM, and as an ELF binary within the Linux user space environment. Support for more execution targets is done by providing more platform libraries that can be chosen during build. Dafna will be fairly free to choose a platform, perhaps based on familiarity or curiosity. Examples for platform choice include bare-metal, ARM, X86_64, VMware, Microsoft Hyper-V, and bhyve.

If you are unfamiliar with Outreachy, it provides three-month internships for people from groups traditionally underrepresented in tech. Interns work remotely with mentors from Free and Open Source Software (FOSS) communities. Xen Project interns have later gone on to work at companies like Oracle, Google and Citrix.

In addition to Outreachy, we are excited to announce a few new interns that will be working on the Xen Project hypervisor through Google Summer of Code. Although the Xen Project was not a mentoring organisation for Google Summer of Code this year, FreeBSD and The Honeypot Project were and had a number of Xen Project related projects. Google Summer of Code is a global program focused on bringing more student developers into open source software development.

Interns that are a part of the Google Summer of Code and working on pushing Xen Project technologies forward include:

  • Kristaps Civkulis who will be working on enabling the EFI loader to load FreeBSD Xen Dom0. There are two parts to the project – you can learn more about it here. The organization supporting this is the FreeBSD Project.
  • Pratyush Yadav who will import the Xen grant-table bus_dma(9) handlers from OpenBSD. FreeBSD Project is supporting Pratyush.
  • Lele Ma who will Port LibVMI to Xen MiniOS. In this project, the core functionalities of the LibVMI will be ported to Xen MiniOS. After ported, Xen MiniOS will have the basic capabilities of introspecting the memory of other guest virtual machines. Honeynet Project is supporting Lele.

Working in open source is a great way to start your career in technology. In a recent survey from HackerRank 84% of respondents (including CEOs, CTOs and company founders) said they look to an applicant’s GitHub project work as an indicator of a prospective employee’s on-the-job skills.

We want to thank everyone who applied to our Outreachy scholarship, and look forward to sharing the accomplishments of our interns. Welcome to open source!

 

Announcing the Xen Project 4.11 RC and Test Day Schedules

On Tuesday, we created Xen 4.11 RC1 and will release a new release candidate every FRIDAY, until we declare a release candidate as the final candidate and cut the Xen 4.11 release. We will also hold a Test Day every TUESDAY for the release candidate that was released the week prior to the Test Day starting from RC1. Note that RC’s are announced on the following mailing lists: xen-announce, xen-devel and xen-users. This means we will have Test Days on April 24th, May 1st, 8th, 15th and 22nd. Your testing is still valuable on other days, so please feel free to send Test Reports as outlined below at any time.

Getting, Building and Installing a Release Candidate

Release candidates are available from our git repository at

git://xenbits.xenproject.org/xen.git (tag 4.11.0-<rc>)

where <rc> is rc1, rc2, rc3, etc. and as tarball from

https://downloads.xenproject.org/release/xen/4.11.0-<rc>/xen-4.11.0-<rc>.tar.gz
https://downloads.xenproject.org/release/xen/4.11.0-<rc>/xen-4.11.0-<rc>.tar.gz.sig

Detailed build and Install instructions can be found on the Test Day Wiki. Make sure you check the known issues section of the instructions before trying to download an RC.

Testing new Features, Test and Bug Reports
