Upcoming: OpenStack workshop at Fedora Flock conference, Prague (Aug 6-9, 2014)

UPDATE: I’ll not be able to make it to Prague due to plenty of other things going on. However, Jakub Ružička, an OpenStack developer and RDO project packager kindly agreed (thank you!) to step in to do the talk/workshop.

Fedora Project’s yearly flagship conference Flock is in Prauge (August 6-9, 2014) this time. A proposal I submitted for an OpenStack workshop is accepted. The aim workshop is to do a live setup of a minimal, 2-node OpenStack environment using virtual machines (also involves KVM-based nested virtualization). This workshop also aims to help understand some of the OpenStack Neutron networking components and related debugging techniques.

Slightly more verbose details are in the abstract. An etherpad for capturing notes/planning and remote participation.

FLOCK 2013, Retrospective


FLOCK just concluded last week. Given the very short time-frame, the conference was very well organized! (I know what pains it takes from first hand experience volunteering to organize FUDCon Pune, couple of years ago). While not undermining others’ efforts, I couldn’t agree more with Spot — “To put it bluntly, anything at Flock that you liked was probably her handiwork.”,about Ruth. Her super-efficiency shined through everything at FLOCK.

I attempted to write while in the middle of a couple of sessions, but I just couldn’t context switch. (For instance, I have a partial draft that’s started off with “I’m currently in the middle of Miloslav Trmač’s discussion about Fedora Revamp…”)

Here’s my (verbose) summary of how I spent my time at FLOCK.

Talks that I have attended

  • Matthew Miller’s discussion of “cloud”, and should Fedora care?: This was a very high level overview of the topic. For me, main takeaway was Fedora’s cloud SIG’s near term goals — more visibility, better documentation.
  • Crystal Ball talk/discussion by Stephen Gallagher which discussed where Fedora is going for the next five years. All the discussion and notes is here.
  • Kernel Bug triage, Live by Dave Jones. Dave walked us through the process of triaging a bug. And also introduced to some scripts he wrote to manage bugzilla workflow, and related triaging aspects.
  • Fedora Revamp by Miloslv Trmac — This was more of a discussion about how to improve various aspects in Fedora. On a broad level, various topics discussed: Making Rawhide more useable, need for more automated tests, etc. Previous mailing list discussion thread is here
  • What’s new with SELinux, by Dan Walsh — Top off my memory, I only recall a couple of things that I recall from this talk where Dan discussed: New confined domains, new permissive domains, sepolicy tool chain, and what’s upcoming (he mentioned a newer coreutils, with upgraded cp, mv, install, mkdir commands which provide -Z flag. Some context is here
  • Secure Linux Containers, by Dan Walsh: This was one of my faviourite sessions. I was interested to learn a bit more about containers. OpenStack heavily uses Network Namespaces to provide Networking, and I thought this session would give some high-level context, and I wasn’t disappointed. Dan discussed several topics: Application Sandboxes, Linux Containers, different types of Linux Namespaces (Mount, UTS, IPC, Network, PID, User), Cgroups. He then went to elaborate on different types of Containers (and their use cases): Generic Application Container, Systemd Application Container, Chroot Application Container, libvirt-lxc, virt-sandbox, virt-sandbox-service, systemd-nspawn.
  • PKI made easy: Ade Lee gave an overview of PKI, Dogtag and its integration aspects with FreeIPA. I worked with Ade on this project and associated Red Hat products for three about years. It was nice to meet him in person for first time after all these years.
  • Fedora QA Meeting : On Monday (12-AUG),I participated in with Adam Williamson and rest of the Fedora QA team. Video is here. Major topics:
    • ARM release criteria / test matrix adjustments
    • Visible Cloud release criteria / test matrix adjustments.

Among other sessions, I also participated in the “Hack the Future” (of Fedora) with Matthew Miller. I also enjoyed the conference recap discussion with FESCo (Fedora Engineering Steering Committee).

OpenStack Test Event

On day two of FLOCK, I conducted an OpenStack test event. Earlier I blogged about it here. This session wasn’t recorded, as it’s a hands-on test event. We had about 20 participants (capacity of the room was arond 25).

Some notes:

  • Russell Bryant, nova PTL, was in the room, not feeling qualified enough, I made him give a quick 5 minute introduction of OpenStack :-). Later, Jeff Peeler from OpenStack Heat project also gave a brief introduction about Heat and what it does. RDO community manager Rich Bowen was also present and participated in the event.
  • Notes from the test event is here.
  • Russel Bryant (Thank you!) kindly offered to provide temporary access to virtual machines (from RackSpace cloud) for participants who didn’t have enough hardware on their laptop, to quickly test/setup OpenStack. I know of at-least a couple of people who successfully setup using these temporary VM instances.
  • A couple of people hit the bogus “install successfully finished” bug. Clean-up and re-run wasn’t really straightforward in this case.
  • Another participant hit an issue where packstack adds ‘libvirt_type=kvm’ in nova.conf /despite/ the machine not having hardware virtualization extensions. It should ideally add ‘libvirt_type=qemu’, if hardware extensions weren’t found (this should be double checked). And, at-least one person hit Mysql login credential errors (which I sure hit myself on one of my test runs) with an allinone packstack run.

Overall: given the time frame of 2 hours, and the complexity involved with setting up OpenStack, we had decent participation. At-least I know 5-7 people had it configured and running. Thanks to Russel, Jeff Peeler, Sandro Mathys, Rich Bowen for helping and assisting participants during the test event.


These are arbitrary discusssions, notes to self, todos, amusing (to me) snippets from hallway conversations. Let’s see what I can recall.

  • I ran into Luke Macken in the hotel lobby, one of the evenings, we briefly talked about virtualization, and he mentioned he tried PCI passthrough of a sound card with KVM/QEMU, and couldn’t get it working. I said, I’ll try and get to him (Note to self: Add this as 198th item on the TODO list).
  • From discussions with Matthew Miller: we need to switch to Oz from Appliance Creator to generate Fedora Cloud images.
  • Try out Ansible’s OpenStack deployer tool.
  • Had an interesting hallway chat with Bill Nottingham, Miloslav Trmac, in the relaxed environment of the Charleston Aquarium (do /not/ miss this mesmerizing place if you’re in Charleston!). Topics: Various Cloud technologies, mailing list etiquette (the much discussed recent LKML epic thread about conflicts, strong language to convey your points, etc.)
  • Books: On day-1 evening dinner, Paul Frields mentioned ‘Forever war’ as one of his favorites and highly recommended it. Next day, during the evening event, at the Mynt bar, Greg DekonigsBerg said, “anything & everything by Jim Collins”. The same evening, while still discussing books, Tom Callaway said “no, that’s not the right book” (or something along the lines) when I mentioned ‘Elements of Style’. I don’t know what was his reasoning was, I liked the book anyway. :-)
  • I learnt interesting details about life in Czech Republic from conversations with Jan Zeleny.
  • A lot of little/long conversations with Adam Williamson (Fedora QA Czar), Robyn Bergeron Ruth Suehle, Christopher Wickert, Rahul Sundaram, Cole Robinson, Toshio Kuratomi, and all others I missed to name here.
  • Thanks Toshio for the delicious Peaches! (He carried that large box of Peaches in the cabin luggage.) Also thank you for the nice conversation on last Tuesday, and taking us to the breakfast place Kitchen, on King’s street.
  • Also, I tried Google Glass from Jon Masters. But it wasn’t quite intuitive, as I have prescription glasses already.

OpenStack test event at Flock — Fedora Contributor’s conference (AUG 9-12)

Firstly, this post should have been coming from Matthias Runge, long time Fedora contributor, OpenStack Horizon developer. Earlier this May, Matthias proposed a FLOCK hack-fest session for OpenStack to test/fix latest packages on Fedora, and it was accepted. Matthias, unfortunately, cannot make it (Duh, he should have been there!) to Charleston due to personal reasons. He trusted I could handle the swap of places with him (I work with him as part of the Cloud Engineering team at Red Hat). Thanks Matthias!

Secondly, it’s not really flash news that FLOCK (Fedora Contributor’s conference), the first edition of the revamped (and now erstwhile) FUDCON, will be taking place in about two weeks (Aug 9-12) in Charleston, South Carolina.

If you care about Open Source Infrastructure as a Service software, and interested in contributing/learning/deploying, you’re more than welcome to participate (needless to say) in this session. There will also be a couple of core OpenStack developers hanging around during the conference!

Some practical information for the OpenStack test event:

  • Abstract: OpenStack FLOCK test event abstract is here.
  • Prerequisites: This is supposed to be a hands on session where we try to setup and test. Given the nature of OpenStack, if you can have a laptop with 4G (or more) memory, and (at-least) 50G of free disk space, it’ll make life easier while setting up OpenStack.
  • Current milestone packages: OpenStack Havana, milestone-2 packages are here.
  • Trunk Packages: These are built from OpenStack upstream trunk on an hourly basis. As of writing this, Neutron (OpenStack networking) server packages are not yet available (coming soon – people are working hard on this!). nova-network is the temporary recommendation. Further details are in the quickstart instructions
  • Bug tracking: If there are OpenStack Fedora/EL packaging, installation & related issues, file it in RH bugzilla. If you’re testing from upstream trunk, it’s better to file them under upstream issue tracker
  • An etherpad instance with more verbose information here. If you have comments/suggestions/notes, please add it there.

Finally, there are plenty of interesting sessions – check out the schedule!

PS: Damn it, Seth Vidal — I was dearly looking forward for your user builds tools talk :( Just noticed Kyle McMartin is doing it on Seth’s behalf.
