I have previously written about oVirt on this blog, but today, the official press release went out. You can read it in full here, but I’d like to quote a bit from the release:
The oVirt project today announced that Canonical, Cisco, IBM, Intel, NetApp, Red Hat and SUSE have joined together to help create a new open source community for the development of open virtualization platforms, including virtual management tools to manage the Kernel-based Virtual Machine (KVM) hypervisor. With the oVirt project, the industry gains an open source, openly governed virtualization stack.
The key piece to note above is the community aspect. oVirt as a community will develop and create an ecosystem in which customers, developers, and vendors can all thrive. Since the workshop, the community has been working towards the first release of oVirt for public consumption. Cisco, being on the oVirt board, is proud to be a part of the oVirt community as this community drives towards the initial release of oVirt.

Let me tell you a reason why open source and open communities are great: information sharing.
Let me explain…
I am Cisco’s representative to the Open MPI project, a middleware implementation of the Message Passing Interface (MPI) standard that facilitates big number crunching and parallel programming. It’s a fairly large, complex code base: Ohloh says that there are 0ver 674,000 lines of code. Open MPI is portable to a wide variety of platforms and network types.
However, supporting all the things that MPI is suppose to support and providing the same experience on every platform and network can be quite challenging. For example, a user posted a problem to our mailing list the other day about a specific feature not working properly on OS X.

In my previous post, I talked about how networking was a large part of the discussion at the oVirt Kickoff Workshop. Increasingly, the network is elevating itself to be a first-class citizen in large open source infrastructure and cloud projects, including open source projects like OpenStack and now oVirt. In OpenStack, the Quantum project is the result of these discussions. Newborn community projects such as oVirt are starting to look at elevating the network to provide advanced functionality as well. It was no surprise a large portion of the last day of the workshop was spent on networking, with an early focus on Quantum.
The last day of the workshop started out the morning with an overview of SDNs and Quantum by Lew Tucker, CTO of Cloud at Cisco. Lew drew a nice overview of cloud networking on the white board, presenting an app-centric view of cloud and virtual networking. In the cloud network model, apps care only about connectivity to the network, not how that connectivity happens, thus the focus on apps as the center of this world.

After Lew was done, Dan Wendlandt, project lead for Quantum, presented his Quantum slides. This was helpful to level-set everyone at oVirt with regards to Quantum and OpenStack. One of the main pain points with looking at how Quantum can be shared from OpenStack into oVirt has been the difference in the networking models. OpenStack presents a very cloud-centric view of networking, whereas oVirt wants a more datacenter-centric model. Quantum was designed to generally be agnostic to the deployment model, so using it in oVirt should be a matter of fitting it into the architecture.

After Dan was done giving a broad Quantum overview, Ram Durairaj from the Cisco OpenStack team presented on Quantum L3 Services. Currently, Quantum is designed to address the L2 abstraction of the network. Quantum L3 Services are meant to expose L3 concepts such as subnets and gateways into Quantum and the plugins. It would also allow for routing between tenant domains.

Now that the oVirt Kickoff Workshop is over, watching how the networking story with oVirt evolves will be interesting. The success of oVirt will be the result of the community around it, and the ecosystem for third party vendors it creates. With regards to networking in oVirt, the interactions between the Quantum community and the oVirt community have only just begun, and the future looks like a very collaborative affair between the two projects.

What if your mobile device allowed you the freedom to seamlessly roam across any network in the world, regardless of location or operator and with all the attributes you would expect, security or privacy… With LISPmob, we may have gotten a giant step closer as we open sourced a network stack for network mobility on Linux platforms, an implementation of basic LISP mobile node functionalities.
This is the Locator Identifier Separation Protocol, which supports the separation of the IPv4 and IPv6 address space following a network-based map-and-encapsulate scheme based on an IETF open standard.
We hope this will be a project and a community many will find not just interesting and vibrant, but necessary and fun to engage, collaborate and contribute.
How will this help your plans to deal with all these amazing possibilities of mobile access to an ever-growing Internet?

Along with several key industry players we announced the formation of and participation in ONF, the Open Networking Foundation with the purpose of promoting a new approach to networking, called software defined networking, open standards based of course, and implicitly open source since all compute loads (or clouds) need and want both, as we are continuously reminded.
