Xen Project Participates in Round 11 of Outreachy

This is a quick reminder that the Xen Project is again participating in Outreachy (Round 11). Please check the round 11 page for more information about the December 2015 to March 2015 round of interships.

Outreach Program for Women has been helping women (cis and trans), trans men, and genderqueer people get involved in free and open source software worldwide. Note that the program has been extended and now also targets people from more groups underrepresented in FOSS: specifically the program is open to residents and nationals of the United States of any gender who are Black/African American, Hispanic/Latin, American Indian, Alaska Native, Native Hawaiian, or Pacific Islander.

Xen Project Test Day for 4.6 RC4 Scheduled for October 1

Our Fourth (and Possibly Final) 4.6 Release Candidate to be Tested This Thursday

TestDayOur Xen Project Test Days help insure that upcoming releases are ready for production, beyond what our automated testing through our Test Lab can accomplish. It is particularly important that our users test out the upcoming release in their own environment. We rely on your functional testing of features, stress-testing, edge case testing, and performance testing to prove that the code is ready for consumption. And this is your opportunity to verify that the new code will continue to work well in your particular situation.

Xen Project 4.6 Release Candidate 4 Testing

Continuing our current release cycle, the Test Day for Xen Project 4.6 RC4 has been set for Thursday, October 1, 2015.

This may be the final RC before release, so the time to test the software is now!

Test Day Information

Test a Release Candidate! Help others, get help! And have fun!

Our Next Test Day is September 15: Xen Project 4.6 RC3

Xen Project 4.6 RC2 Test Day is September 1, 2015

Join 4.6 Release Candidate Testing on September 1, 2015

39833137_mAlthough the Xen Project performs automated testing through the project’s Test Lab, we also depend on manual testing of release candidates by our users. Our Test Days help insure that upcoming releases are ready for production. It is particularly important that our users test out the upcoming release in their own environment. In addition, functional testing of features (in particular those which can’t be automated), stress-testing, edge case testing and performance testing are important for a new release.

Xen 4.6 Release Candidate Testing

A few weeks ago, Xen 4.6 went into code freeze and Xen 4.6 RC2 is now ready for testing. With this in mind the Test Day for Xen 4.6 RC2 has been set for next Tuesday, September 1, 2015.

Subsequent Test Days are expected to be scheduled roughly ever other week until Xen 4.6 is ready for release.

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.

XPDS15


Andrew Cooper from Citrix is giving an introduction of Migration v2 in Xen 4.6. Check out the PDF and video.

Session Recordings and Slides

Most of the slides are already available as PDFs on the event website. We will re-post the slides later on our slideshare channel and on the Xen Project Website.

Video recordings of the conference sessions are already posted on our youtube channel and will also be posted on the Xen Project Website. Check out some of my personal highlights:

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.
