The researchers at Washington University in St. Louis and University of Pennsylvania are pleased to announce, here on this blog, the release of a new and greatly improved version of the RT-Xen project. Recent years have seen increasing demand for supporting real-time systems in virtualized environments (for example, the Xen-ARM
Yes, today (Tuesday, October 8th) is one of the Fedora 20 Test Days, more specifically, Virtualization Test Day. Specific information regarding testing Xen on the new Fedora can be found in this Wiki page. For attending and participating, join us now on IRC at #fedora-test-day (Freenode)! Fedora 20 will be
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
Here is an update about feature completeness of QEMU compared to the old qemu-traditional. But first, what is the difference between QEMU and qemu-traditional? QEMU is the software that can be found at qemu.org, we can also call it QEMU upstream. It’s where all new features are supposed
One of the stated goals for 2013 and 2014 of the Xen Project Advisory Board is to Increase upstream Xen Hypervisor quality including the quality of its latest CPU and Platform features and to address problems with the code in a timely and proactive manner, including defects, security vulnerabilities and
The following monologue explains how Linux drivers are able to program a device when running in a Xen virtual machine on ARM. The problem that needs to be solved is that Xen on ARM guests run with second stage translation in hardware enabled. That means that what the Linux kernel
Some time ago Konrad Rzeszutek Wilk (the Xen Linux maintainer) came up with a list of possible improvements to the Xen PV block protocol, which is used by Xen guests to reduce the overhead of emulated disks. This document is quite long, and the list of possible improvements is also
My name is Julien Grall.  I joined the Citrix Open Source team few months ago to work on Xen on ARM with Ian Campbell and Stefano Stabellini. Since Citrix has joined the Linaro Enterprise Group (LEG), I’m also part of the virtualization team which takes care of Xen,
So, how many of you use Debian? I bet a lot. Well, here it is what the Debian Xen package maintainers told The Xen Project, when asked a few questions. We are talking about Bastian Blank and Guido Trotter. In fact, they share the burden, with Bastian doing “most of
Xenproject.org is pleased to announce the release of Xen 4.3.0. The release is available from the download page: * Xen 4.3.0: Download, Source (tag RELEASE-4.3.0), release notes. Xen 4.3 is the work of just over 9 months of development, with 1362 changesets containing
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). Fortunately that’s now fixed (see the most important patch of that series) and the back-porting process to stable
As it is widely know, really tough Open Source users –the ones that wear sandals, colored hats of various kind, and are equipped with long enough UNIX beards— always install software via tarballs and some good old ./configure-make-make-install-fu! Then there are the developers, who couldn’t care less about installing:
