Creedence Release Candidate Available

Just in time for the holiday season - we're pleased to announce a another tech toy for the geeks of the world to play with. Now of course XenServer is serious business, but just like many kids toys, the arrival of Creedence is eagerly awaited by many. As I mentioned earlier this week, you'll have to wait a bit longer for the official release, but today you can download the release candidate and see exactly what the world of Creedence should look like. Andy also mentioned last week that we're closing out the alpha/beta program, and as part of that...

Mature Open Source Projects: Centers of Continuing Innovation?

Recently, I attended a conference session where the presenter said of his mature project, "We are focused mostly on performance these days, not much on new stuff."  To most people, I'm sure this statement was unremarkable.  However, as one who is associated with a project which is over a decade old and powers many of the largest clouds in the world, I found the statement both sobering and horrifying. It is sobering to think that lack of  innovation within a project speaks of the impending end of the effort; a race has been run, a finish line crossed, and a horse...

Running Nova-Docker on OpenStack Juno (CentOS 7)

Quote ([2]) :- The Docker driver is a hypervisor driver for Openstack Nova Compute. It was introduced with the Havana release, but lives out-of-tree for Icehouse and Juno. Being out-of-tree has allowed the driver to reach maturity and feature-parity faster than would be possible should it have remained in-tree. It is expected the driver will […]

Status of Creedence

Over the past few weeks, and particularly as part of the Creedence World Tour, I've been getting questions about precisely when Creedence will be released. To the best of my ability, I've tried to take those questions head on, but the reality is we haven't been transparent about what happens when we release XenServer, and that's part of the problem. I'm going to try and address some of that in this post. Now before I get into too much detail, it's important to note that XenServer is a packaged product which Citrix sells, and which is also available freely as open...

The dangers of free software

This is part of a 3 piece entry, the cover of which is: free software patents and cosmos There are serious dangers with free software and open source software which I'd like to review. Some zealots may tell you that there is nothing to worry about when embracing free software and open source software but I'm here to tell you that this is all wrong, explain where all this badness comes from and give some advice about what you can do about it. I will do this by providing a brief summary on the efforts on transforming a non upstream...

The Free Software patent paradox

This is part of a 3 piece entry, the cover of which: free software patents and cosmosOn my last post I reviewed the rapid pace of evolution of free software, open source software and legal evolutions and the implications for business models. There is an interesting set of problems which arise in light of all these evolutions in consideration of personal freedoms, existing business models and patents which I'd like to review now which in the worst case scenario make free software and open source software targets. I'll refer to this as the free software patent paradox. A paradox, as...

Cosmic evolution of free software

This is part of a 3 piece entry, the cover of which is: free software patents and cosmos.There is a relationship between cosmology, singularity and free software and even surveillance which this post dares to consider which I will use to try to remove any fear, uncertainty and doubt over the evolution of free software and open source software but also to provide clarification of why business models must become dynamic and adaptable. I remember watching Carl Sagan's 1980 Cosmos: A Personal Voyage for the first time when I was a kid but I only remember things vaguely....

Xen Project Contributor Training

A few weeks ago, I went onto a road trip to China with the aim to meet Xen Project users as well as contributors. When I was planning the trip, it became apparent that many of the developers in China are new to the project and had difficulties with Xen Project governance and how the […]
