Introducing Xen Project’s New Test Lab

One of Xen Project’s highest priorities is to continually work to improve the quality of our code and code coverage. We’re serious and proactive when it comes to minimising and, whenever possible, eliminating any adverse effects from defects, security vulnerabilities or performance problems. Our users run some of the largest cloud and datacenter operations in the world, so we know that reboots and service interruptions are more than mere glitches in operations.

Redhat Cluster and Citrix XenServer

I wanted to write down a guide for RHCS on RHEL/Centos6 and XenServer.
If you want to do that, you need to go through two major challenges which you will encounter. I want to save on the search and sum it all up together here.

A Tale of Two Amazing Open Source Hypervisors

Born in the logic of ones and zeroes and forged in the heat of battle, two hypervisors–sworn foes in the realm of virtualization–are about to unite in a way many never thought possible. Over beer and code.

Xen Project Participates in Outreachy (formerly OPW)

This is a quick reminder that the Xen Project is again participating in Outreachy (formerly known as OPW/Outreach program for Women).

Outreachy is the successor of the Outreach Program for Women. Please see its page for the information about the May 2015 round of interships.

Timeout when using Ricci as the backend for Corosync update in Redhat Cluster

When using Ricci as the engine for ‘cman_tool version -r’ command, you will experience timeouts (and practically – you will be unable to use ricci to update the cluster configuration across the nodes) when the ricci user password contains XML-sensitive characters, like <>&, etc.
As they say – FYI

Future of Xen Project: Video Spotlight Interview with Cavium’s Larry Wikelius

With several companies introducing ARM servers recently, cloud providers and enterprise datacenters are excited to see new alternatives for reducing costs and power use come to market. Cavium, a semiconductor leader with a long heritage in security and wireless/ networking, entered the race with the introduction of ThunderX™ the industry’s first 48-core and 96-core family of ARMv8 workload optimized processors.

Xen Project Now an Easy Option in OpenStack

Recent Changes Let Xen Project Work Out of the Box in OpenStack

Members of the Xen Project development team have always believed that the hypervisor must be available for integration into other Open Source projects.  In particular, the initiators of the Xen Project envisioned the day when compute resources would be available in a dynamic form, which has since been codified in the technology we now call Cloud Computing.
