Happy Birthday CentOS!

Today, CentOS turns 15 years old. It’s had hard times and good times, and gone through a number of big changes over those years. We feel that we’ve landed in a really great place over the last five years, as part of the Red Hat family of projects, and we’re very excited about what’s coming with CentOS 8, and the years to come.

Right now, we want to look back at how we got where we are now. We did that by going back and talking with some of the people that were involved in those early years, as well as some that joined the project later on. Continue reading

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.

Description: A free software project primarily responsible for the creation of the enterprise-ready Linux distribution CentOS.

The Open Source and Standards (OSAS) team at Red Hat helps support a number of diverse projects and their communities, and that number is growing alone with the responsibilities of the team. To highlight the projects with which OSAS works, a new series of community profiles will highlight the projects and the people who work with them. To start the series, we’ll examine the CentOS Project–likely the most unique project within the OSAS ecosystem.

RDO and CentOS

Continuing in the series about the RDO Meetup in Vancouver, in this recording we have Karsten Wade, of the CentOS project, talking about CentOS’s relationship with RDO, and with OpenStack in general. He talks about the CentOS build infrastructure, CI, package repos, and the CentOS Cloud SIG.

FOSDEM 2015 Video Archives Now Online

Despite a few hiccups in the live streaming and recording efforts at FOSDEM 2015, 402 talks were successfully recorded, 94 of which popped up in the video archives this week. The archives also include recordings from past FOSDEMs (all the way back to 2005), so when you discover that you’ve been sitting at your computer for a few days, watching videos and tripping down memory lane, don’t say I didn’t warn you.

Here are a few of the many 2015 videos you might want to check out:

FOSDEM organizers are still editing and posting videos, so keep an eye on the 2015 video folder or check the STATUS text file for additions.

RDO at the CentOS Dojo

On the Friday before FOSDEM, we gathered at the IBM offices in Brussels for the CentOS Dojo.

This morning, Haikel Guemar led a hands-on RDO tutorial, in which he presented some basic information about RDO, and then provided instructions to install RDO, and several of us walked around ensuring that it was all going well.

Due to time, as well as VM limitations, we installed a subset of the entire OpenStack packages – just Nova, Glance, Keystone, Neutron, and Horizon. (Optionally, Swift.)

Also, rather than using the repo referenced in the RDO QuickStart, we used the newly available repo on the CentOS build system: http://buildlogs.centos.org/centos/7/cloud/openstack-rdo/centos-cloud-rdo.repo. This was done to demonstrate our ongoing move to packaging RDO via the CentOS Cloud SIG.

Following Haikel’s presentation, Jakub Ruzicka talked about ways to participate in the RDO project. Jakub talked about the RDO Packaging Guide, and mentioned several places that people could get involved, including the effort to package OpenStack for CentOS 6.

We had perhaps 30 people in attendance, and it looked like at least a dozen people made it successfully through deploying RDO, which was encouraging; however, Haikel and I talked afterwards about what we might do to make events like this more successful in the future. If you were in attendance and have any suggestions, please send your comments to the rdo-list mailing list, so that we can help more people have a successful experience.

Planning for Developer Conference 2015

Many of us are finalizing our FOSDEM plans and preparing to head to Brussels, then we’ll have a few days to recover before DevConf.cz starts in Brno. Planning ahead for DevConf.cz, here’s a preview of some of the upstream project talks.

After Tim Burke’s keynote, The Future of Red Hat, DevConf.cz attendees will have a schedule full of great technical talks to choose from, including:







Project Atomic


Plus talks on Using Ansible for community-managed infrastructure, Software Collections, delivering open source projects using Agile & DevOps thinking, and more.

See the full DevConf.cz schedule at: http://www.devconf.cz/schedule.

Swimming Upstream

For the first year and a half, RDO has been largely an effort run by Red Hatters, with some of the work going on behind the firewall. In our community meetup in Paris, at the OpenStack Summit, as I mentioned in my earlier post, we got a lot of feedback from people saying that they wanted greater insight into what we were doing, as well as the opportunity to play along.

So I wanted to quickly update with some of the things that we’re doing in RDO to "swim upstream" a little more.

CentOS Cloud SIG

The CentOS Cloud SIG is moving along, although officially still in the "getting started" phase. We’ve started having weekly meetings on IRC, on the #centos-devel channel on Freenode. Those meetings are at 15:00 UTC every Thursday. (date -d "15:00 UTC" in your favorite shell will translate that to local time for you.) Have a look at the minutes from our most recent call and plan to attend the next one.

The Cloud SIG isn’t just RDO, though. It also incorporates work in the Eucalyptus community, and other cloud provider projects have expressed interest, too.

RDO Packaging Meetings

In addition to the work that’s happening in the CentOS Cloud SIG, there’s also the RDO-specific work that happens outside of CentOS, and for that we have a bi-weekly meeting where you can find out what’s happening, and where you can get involved. These happen on the #rdo channel on Freenode IRC, every other Wednesday, also at 15:00 UTC. You can see the minutes from the most recent meeting, and we hope to see you at the next one.


And, on the same subject, if you plan to be at FOSDEM next week, RDO will be represented at the CentOS dojo. Haikel Guemar will be leading a demo of the RDO Quickstart, where you can see, and play along, as he deploys OpenStack on CentOS 7. If you’re planning to attend, Haikel offers the following advice:

In order to run the tutorial on your machine, we recommend a VM on your laptop that has 20GB+ of disk space, 2GB of ram and atleast 1 dedicated cpu core. If your laptop has the ability to run nested-virt, please enable that and use it. It will make a large difference to performance of the overall setup. We would also like to request everyone to setup these VMs ahead of time, in either KVM or Xen or any other virtualisation technology you might use. A basic CentOS-7 minimal install is sufficient to start from.

Come swim with us

There are lots of places where you can get involved in OpenStack. We’d love to have you participate in what we’re doing at RDO. Come along to one of the meetings, and see if there’s something you can contribute to the effort. Although we’re heavily Red Hat at the moment, we really want participation from the broader community of Fedora and CentOS users.

We hope to see you soon.

RDO Quickstart: Doing the Neutron Dance

RDO, the community-oriented OpenStack distribution for CentOS, Fedora, and their kin, is super-easy to get up and running, as a recently posted YouTube video illustrates:

At the end of the process, you’ll have a single-node RDO installation on which you can create VM instances and conduct various experimentation. You can even associate your VMs with floating IP addresses, which connect these instances to the "Public" network that’s auto-configured by the installer.

BUT, that’s where things stop being super-easy, and start being super-confusing. The auto-configured Public network I just mentioned will only allow you to access your VMs from the single RDO machine hosting those VMs. RDO’s installer knows nothing about your specific network environment, so coming up with a more useful single-node OpenStack installation takes some more configuration.

Collaboration with CentOS is a Win-Win for oVirt

Normally within the oVirt release cycle, we don’t offer new features in mid-cycle. Instead, we just improve upon or fix up the features that are already in there, and new features will come out the next major point release. But last week we announced the oVirt 3.5.1 release candidate, and we’re pleased to confirm that oVirt Engine will indeed run on el7 distributions, which includes Red Hat Enterprise Linux and CentOS 7.

As of this RC, oVirt packages for oVirt are now available for Fedora 20, el6, and el7.

There are two big reasons why this new functionality was added in mid-cycle. The first was straightforward: Users wanted it. A lot. As soon as 3.5 came out, there were many requests (online and face-to-face) that amounted to: When will Engine run on CentOS 7? That kind of community demand deserves a lot of attention.

The second reason was more strategic, and no less important. Recently, oVirt joined the CentOS Virtualization Special Interest Group (Virt SIG), and being a part of this SIG gets oVirt a lot of collaborative capability with the CentOS Project.

Initially being in the Virt SIG was attractive for the oVirt Project because we were looking for a way to ensure that the qemu-kvm package in CentOS would have live snapshot capability enabled. This flag is not usually set to enabled by default. But there are other benefits. Our oVirt Live ISO images use CentOS 6 packages as their base with Kickstart files from Scientific Linux. In the SIG, oVirt can make oVirt Live fully CentOS-based and eventually move to CentOS 7.

oVirt Node is a small, robust operating system image using minimal resources, while providing the capability to control virtual machines. Node is based on CentOS as well, and it makes a lot of sense to stay active in the Virt SIG.

oVirt is happy to participate in the Virt SIG with CentOS and other virtualization projects, and we’re looking forward to gaining the benefits of closer collaboration in the broader virtualization community.
