Free As In (Lots of) Speech

scale14x logo At first blush, the Southern California Linux Expo (SCaLE) and the Free and Open Source Software Developers' European Meeting (FOSDEM) would seem to be as far apart as the 5611 miles that separate them. Sure, they have some surface similarities–they are both in late January, many of the same projects are showcased at each event, and there is Linux everywhere.

But look a bit past that and you will see two events that represent community within the free and open source ecosystem in sharply different ways.

FOSDEM Notes—Examining Live VM Migration

qemu logo The notion that all virtualization workloads and use cases are the same is not widespread in IT, but it remains an idea that is somewhat hard to shake. In point of fact, the differences in how virtual machines are deployed and run can be seen in the existence of differing platforms like OpenStack, oVirt, and virt-manager.

All three of these platforms use the KVM hypervisor, but their target use cases are clearly very different. Cloud, datacenter management, and single-server virtual machine management satisfy very different needs, and getting KVM to cater to those needs has proven to be a challenge over the years.

FOSDEM Notes—Revving QEMU Performance

KVM logo The KVM hypervisor has always been at or near the top of any sort of performance chart in virtualization land. But when it comes to disk input/output, things are not as always so well behaved.

In terms of block storage, KVM can fall short in performance, because the hypervisor is tapping into the QEMU block layer, not the Linux kernel. And when large blocks come through, things can slow way down, according to Paolo Bonzini, a Senior Principal Software Engineer at Red Hat and maintainer for the KVM Project.

Community Track at Red Hat Summit Call for Proposals

This year at Red Hat Summit, we will have a track to highlight some of the excellent work being done in upstream communities that Red Hat participates in and sponsors. If you're working on, or using, one of our key projects we'd love to hear about it!

The Open Source and Standards (OSAS) team would like to feature interesting case studies that show how our communities are using projects like CentOS, Ceph, Fedora, Foreman, Gluster, oVirt, Project Atomic, RDO, and others. We're also interested in presentations that show off work happening in the upstreams, to demonstrate the innovation that happens first upstream.

FOSDEM Notes—Introducing Lago

Lago logo There's a lot of movement lately around containers to run tests and development environments, but not all the applications are ready to run inside them, maybe because they are legacy applications, that rely on some system details to be able to run, or because they are applications that require to access those system details, like for example, oVirt, a virtualization platform for the data center.

So in oVirt, we found that containers were not a strong fit to create reproducible and meaningful testing environments that would give insight on the possible failures when running on real metal. We wanted an easy way to let developers run those tests locally on their laptops the same (or as similar as possible) way as they run on continuous integration, where we have big servers. Here is where the Lago project comes in play!

Ceph Community Update—January 2016

Ceph logo It has been quite a while since a coordinated Ceph update has made it to the Ceph blog, so I figured it was time to gather all of the various threads and make sure they were in a single place for consumption.

Quite a lot is happening in the Ceph world and, depending on what part of the project you are involved with, there is more than likely to be a place for you to deepen your engagement with the community. So, let’s do the highlight reel.

Welcome to the New Project Atomic Community Lead

Project Atomic logo The Open Source and Standards team in Red Hat is very pleased to announce the addition of its latest team member: Josh Berkus, the new Community Lead for Project Atomic.

It is probably not hyperbole to say that Josh's life is all about containers right now… almost literally. Not only is Josh taking on the new role at Red Hat for Project Atomic, which is all about managing and optimizing containers, he and his wife are in the process of transporting their residence from the Bay Area to Oregon this month–appropriately enough, using shipping containers.

A Celebration of Language Community Work

FUEL logo The FUEL Project is one of the rare projects that emanated from India and is now associated with various language communities and organizations across the world.

The FUEL GILT Conference is an annual event started by FUEL Project in 2013 that gives an opportunity to its participants to hear experts on various topics related to language technology. This was the third FUEL GILT Conference and, like previous events, it was all about showcasing and celebrating efforts being taken by individuals, organizations, and open language communities. Topics included, but were not limited to, Globalization, Localization, Internationalization, and Translation (GILT). This is the one of largest events across the globe that concentrates on GILT technology.
