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.
  • Honeynet Project is also supporting Stewart Sentanoe who is working on stealth monitoring with Xen altp2m based on previous work that has been done – see here. And Ulrich Fourier who is working on adding support for ARM introspection, which is a follow-up to a 2016 GSoC project that developed altp2m support to Xen on ARM.

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

You can find Test Instructions for new features on our Test Day Wiki and instructions for general tests on Testing Xen. The following pages provide information on how to report successful tests and how to report bugs and issues.

Happy Testing!

Join us at Root Linux Conference Happening in Kyiv, Ukraine This April!

Root Linux Conference is coming to Kyiv, Ukraine on April 14th. The conference is the biggest Linux and embedded conference in Eastern Europe with presenters exploring topics like: Linux in mobile devices, wearables, medical equipment, vehicles, and more. Want to learn about the next generation of embedded solutions? This is the conference for you.

Juergen Gross, Linux Kernel developer at SUSE, and Paul Durrant, Senior Principal Software Engineer at Citrix Systems, are keynoting the conference. Juergen will cover Xen paravirtualized (PV) devices and Paul will cover Intel GVT-g integration into XenServer.

Early bird priced tickets for the event are still available here.

See you there!

Xen Project Contributor Spotlight: Yurii Konovalenko

The Xen Project is comprised of a diverse set of member companies and contributors that are committed to the growth and success of the Xen Project Hypervisor. The Xen Project Hypervisor is a staple technology for server and cloud vendors, and is gaining traction in the embedded, security and automotive space. This blog series highlights the companies contributing to the changes and growth being made to the Xen Project, and how the Xen Project technology bolsters their business.

Name: Yurii Konovalenko
Title: Project Manager
Company: GlobalLogic

When did you start contributing to the Xen Project?
GlobalLogic started to contribute to the Xen Project in 2013. Since that time, we have done a significant job to improve the overall functionality of the Xen Project with respect to the embedded world. For example, we brought to life R_CAR platform support from Renesas.

How does contributing to the Xen Project benefit your company?
There are many benefits of contributing to the Xen Project, a few of the most important ones for us, include:

  • Simplified community support of the features GlobalLogic has contributed.
  • Promotion and advertising of GlobalLogic expertise to the world.
  • Extension of internal GlobalLogic experience by connecting to experts in different domains.
  • Possibility to develop internal knowledge and find new bright ideas about different challenges due to being an active member of the OSS community.

How does the Xen Project’s technology help your business?
Most of GlobalLogic projects in the automotive area are based on the Xen Project hypervisor. It is extremely flexible and able to satisfy the requirements of all our customers. Nowadays, GlobalLogic is a leading player in this domain. A lot of OEMS and Tier 1 companies are currently looking into hypervisor solutions. The Xen Project hypervisor is a perfect platform for such solutions and taking into account a collaboration between GlobalLogic and the Xen Project, a lot of potential customer contact GlobalLogic with different requests in this area. All of it leads to constant GlobalLogic business growth in the area of the hypervisor (and the Xen Project hypervisor in particular).

What are some of the major changes you see with virtualization and the transition to cloud native computing?
Nowadays, redistributed cloud-based solutions is really a trend. It is one of the additional advantages of using Xen Project technologies. Based on this platform, it is easy to build these systems. For example, microservice architecture provides very powerful and flexible tools for building scalable and reliable cloud-based solutions.

In addition, we are seeing the following trends unfold:

  • Less computing is done on board, more in cloud.
  • Platform agnostic systems become more widespread.
  • Embedded systems are gaining higher capabilities.

What advice would you give someone considering contributing to the Xen Project?
Don’t hesitate to reach out for consultation with domain owners before submitting feature implementations or new platform support. They can recommend the best way to satisfy the requirements with minimum efforts.

What excites you most about the future of Xen?
As for now, we see the following exciting challenges:

  • Safety certification for automotive industries.
  • Internal communication security (IPC, RPC, Rtrast Zone etc.).
  • Support of extensions from ARM.
  • Intel embedded systems support.
