The hypervisor team has come to the conclusion that using the C programming language, which is 45 years old as of writing, is not a good idea for the long term success of the project. C, without doubt, is ridden with quirks and undefined behaviours. Even the most experienced developers
I’m pleased to announce the release of the Xen Project Hypervisor 4.8. As always, we focused on improving code quality, security hardening as well as enabling new features. One area of interest and particular focus is new feature support for ARM servers. Over the last few months, weâ€
Dear community members, I’m pleased to announce that Julien Grall <julien.grall@arm.com> will be the Release Manager for the next Xen release. The appointment was voted by the Committers and the vote passed. Julien has done excellent jobs in many aspects. He has been an

Xen has long history and many features. Sometimes even experienced developers cannot be sure whether their new code is regression-free. To make sure new code doesn’t cause regression, Ian Jackson developed a test framework called OSSTest. In order to make this framework usable for individual ad-hoc testing, standalone mode
As many of you might have (inevitably) noticed, Xen frontend / backend network drivers in Linux suffered from regression several months back after the XSA-39 fix (various reports here, here and here).
