CentOS has cemented a reputation as the "community enterprise operating system" - one that provides a reliable rebuild, but is not known for innovation in its own right. With the news that Red Hat and CentOS are joining forces, this is going to change. Here's how CentOS is planning to change, and how other distros can learn from our next phase.

This includes our governance changes, and how we'll address several different special interest groups (SIGs) that have different ideas they want to realize with CentOS. It also includes technical changes, and I'll explain how we're going to manage our build system and source control for accepting upstream code and then creating new variants.

Most importantly, I'll also be taking questions about the new direction and how we got to this point.

The present status of Cloud and Virtualised Machine instances is very chaotic; different Vendors doing their own thing, every hypervisor needing its own magic and various cloud instances imposing their own site requirements. The RainDrops project aims to reduce the impact this has on users, giving them a unified interface ( web, git and REST ) that they can define their requirements against. And let the system handle the various requirements.

In this presentation we aim to define the scope of the problem and demonstrate our solution. Our demo will consist of defining a single kickstart file, and then using that to build multiple instances for different vendors and technologies, with very little effort and no vendor specific configs needed.

The raindrops project has been in development and closed testing upto this point, we hope to use the Fosdem talk to launch it publicly.

In this talk we will discuss how the build system and QA of CentOS is implemented using a private cloud: OpenNebula. We will focus on the challenges of integration, advantages and workflow. We will also demonstrate how to implement and automate a building system and QA tasks by creating a private cloud on the fly with a CentOS laptop using OpenNebula. Administrators will benefit from this technique -and its simplicity and ease of deployment- to overcome the complexity of this kind of systems.

In this talk, I will cover the work done, the targets and deliverables for Xen on CentOS-6 project and how this maps to the future of virtualisation on the CentOS platform. I will also cover potential migration options for people who have CentOS-5/Xen stacks operational at this point.

With the release of Red Hat Enterprise Linux 6, a decision was made at their end to drop support for dom0 / host level support for Xen; The CentOS linux Distribution follows the upstream mandate as close as possible - and therefore we lost Xen support as well. Now, a small group of people have brought Xen/CentOS-6 together again to address the needs of users who had invested in Xen on CentOS-5 as well as new adopters looking at Xen as a KVM alternative.

In this talk, I will cover the work done, the targets and deliverables for this Xen on CentOS-6 project and how this maps to the future of virtualisation on the CentOS platform. I will also cover potential migration options for people who have CentOS-5/Xen stacks operational at this point.
