RDO at DevConf.cz, FOSDEM

In the coming two weeks, RDO will have a presence at three different events in Europe, and we’re hoping to see you there.

On January 27th through 29th, we will have a table at DevConf.cz in Brno, Czechia. Drop by to pick up RDO stickers, command line cheat sheet bookmarks, and RDO tshirts.

There will also be a number of OpenStack presentations, including:

  • Zuul v3: OpenStack and Ansible Native CI/CD, by James Blair
  • OpenStack with Kubernetes: better together, by Pete Birley
  • Auto Provisioning IdM clients in OpenStack, by Rob Crittenden
  • Shell-Scripting my way through OpenStack, by Pily Sutter
  • Image builds with diskimage-builder and ansible, by Paul Belanger
  • Skynet your Infrastructure with QUADS + Foreman, by Will Foster
  • Putting your OpenStack in your containersm by Flavio Percoco

The following Friday, February 3rd, in advance of FOSEM in Brussels, Belgium, RDO will have talks at the CentOS Dojo at the Marriott Grand Place. These include:

  • OpenStack @ CERN: Status update, by Spyros Trigazis
  • CI in the cloud – How RDO uses OpenStack infra tools for packaging, by Haïkel Guémar and Matthieu Huin

And then on February 4th and 5th, come see us at the table that we’ll be sharing with CentOS in the expo are at FOSDEM. There will be OpenStack talks in the virtualization devroom, and we’ll be helping out at the OpenStack table on both Saturday and Sunday,

So come join us, or, if you can’t follow us on @rdocommunity for photos and updates from these events.

oVirt Rolls Into FOSDEM

fosdem logo Last month I was honored to experience my first FOSDEM as a devroom manager, for the Virtualization & Infrastructure-as-a-Service room. Despite my previous experience running open source events and my experience with FOSDEM as an attendee, running a devroom was a whole new beast, due to the sheer size of the conference and the broad scope of the devroom content.

The 500-person room was really well-attended, with many interesting talks about areas such as KVM/QEMU, libvirt, OpenStack, oVirt, Xen, and container integrations. For the most part, we had around 80% capacity, with notable exceptions being Containers and Virtualization by Joe Brockmeier, which packed the room to capacity, as well as I Find Your Lack of Threads Disturbing by Paolo Bonzini and Oh My! Oh My Vagrant by James Shubin, both of which came as very close runner-ups.

RDO Community Day at FOSDEM

RDO logo Time does get away from me! It’s been three weeks now since I was in Brussels for FOSDEM. On the day before FOSDEM started, we held the first RDO Community Day as part of the CentOS Dojo. (Mark your calendars, we’re definitely doing this again next year!)

Rewinding a little… last year at FOSDEM, we had a few RDO presentations as part of the CentOS Dojo. This was very well received, and at the RDO meetup at the OpenStack Summit in Vancouver, we decided to make it into a whole day.

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.

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!

oVirt Goes to FOSDEM16

oVirt logo With FOSDEM 2016 just a few short weeks away, here are all the details about our community activities during the conference.

As previously mentioned in this blog post, the devroom schedule is available on the FOSDEM website. We have some great presentations from our community members, with something for everyone to learn from and enjoy throughout both days of the conference.
