Upcoming events

There's a number of upcoming events where RDO enthusiasts will be present. Mark your calendar!

Join us for Test Day!

Milestone 3 of the Pike cycle was released last week, and so it's time to test the RDO packages. Join us on Thursday and Friday of next week (August 10th and 11th) for the Pike M3 test day. We'll be on the #RDO channel on the Freenode IRC network to test, help, answer questions, and propose solutions.


We encourage you to attend your local OpenStack meetup. There's hundreds of them, all over the world, every day. We post a list of upcoming meetups to the RDO mailing list each Monday, so that you can mark your calendar. Or you can search meetup.com for events near you.

If you're going to be speaking at an OpenStack meetup group, and you'd like to have some RDO swag to take along with you, please contact me - rbowen@redhat.com - or Rain - rain@redhat.com - with your request, at least two weeks ahead of time.

And if you're a meetup organizer who is looking for speakers, we can sometimes help you with that, too.

OpenStack Days

The following OpenStack days are coming up, and each of them will have RDO enthusiasts in attendance:

If you're speaking at any of these events, please get in touch with me, so that I can help promote your presence there.

Other Events

The week of September 11 - 15th, the OpenStack PTG will be held in Denver, Colorado. At this event, project teams will meet to determine what features will be worked on for the upcoming Queens release. Rich Bowen will be there conducting video interviews, like last time, where OpenStack developers will be talking about what they worked on in Pike, and what to expect for Queens. If you'll be there, watch the announcements from the OpenStack foundation for how to sign up for an interview slot.

On October 20th, we'll be joining up with the CentOS community at the CentOS Dojo at CERN. Details of that event may be found on the CERN website. CERN is located just north of Geneva. The event is expected to have a number of RDO developers in attendance, as CERN has one of the largest OpenStack deployments in the world, running on RDO.

Other RDO events, including the many OpenStack meetups around the world, are always listed on the RDO events page. If you have an RDO-related event, please feel free to add it by submitting a pull request on Github.

Here's some of the great blogs from the RDO community which you may have missed in recent weeks:

Using NFS for OpenStack (glance,nova) with selinux by Fabian Arrotin

As announced already, I was (between other things) playing with Openstack/RDO and had deployed some small openstack setup in the CentOS Infra. Then I had to look at our existing DevCloud setup. This setup was based on Opennebula running on CentOS 6, and also using Gluster as backend for the VM store. That's when I found out that Gluster isn't a valid option anymore : Gluster is was deprecated and was now even removed from Cinder. Sad as one advantage of gluster is that you could (you had to ! ) user libgfapi so that qemu-kvm process could talk directly to gluster through ligbfapi and not accessing VM images over locally mounted gluster volumes (please, don't even try to do that, through fuse).

Nested quota models by Tim Bell

At the Boston Forum, there were many interesting discussions on models which could be used for nested quota management (https://etherpad.openstack.org/p/BOS-forum-quotas).Some of the background for the use has been explained previously in the blog (http://openstack-in-production.blogspot.fr/2016/04/resource-management-at-cern.html), but the subsequent discussions have also led to further review.

OpsTools on RDO

OpsTools for RDO


In the CentOS community there are Special Interest Groups (SIG) that focus on specific issues such as cloud, storage, virtualization, or operational tools (OpsTools). These special interest groups are created to either to create awareness or to tackle the development of that subject with focus. Among the groups there is the Operational tools group (OpsTools) that focus on

  • Performance Monitoring
  • Availability Monitoring
  • Centralized Logging

OpenStack Operational Tools

While the OpsTools are created for the CentOS community, it is also applicable and available for RDO. More information can be found at GitHub.

Centralized Logging

The centralized logging has the following components:

  • A Log Collection Agent (Fluentd)
  • A Log relay/transformer (Fluentd)
  • A Data store (Elasticsearch)
  • An API/Presentation Layer (Kibana)

With the minimum hardware requirement:

  • 8GB of Memory
  • Single Socket Xeon Class CPU
  • 500GB of Disk Space

Detailed instruction to install can be found here.

Availability Monitoring

The Availability Monitoring has the following components:

  • A Monitoring Agent (sensu)
  • A Monitoring Relay/proxy (rabbitmq)
  • A Monitoring Controller/Server (sensu)
  • An API/Presentation Layer (uchiwa)

With the minimum hardware requirement:

  • 4GB of Memory
  • Single Socket Xeon Class CPU
  • 100GB of Disk Space

Detailed instruction to install can be found here.

Performance Monitoring

The Performance Monitoring has the following components:

  • A Collection Agent (collectd)
  • A Collection Aggregator/Relay (graphite)
  • A Data Store (whisperdb)
  • An API/Presentation Layer (grafana)

With the minimum hardware requirement:

  • 4GB of Memory
  • Single Socket Xeon Class CPU
  • 500GB of Disk Space

Detailed instruction to install can be found here.

Ansible playbooks for deploying OpsTools

Besides manually install the OpsTools, there are Ansible roles and playbooks to automate the installation process and instructions can be found here.

Create a TripleO snapshot before breaking it… by Carlos Camacho

The idea of this post is to show how developers can save some time creating snapshots of their development environments for not deploying it each time it breaks.

Tuning for Zero Packet Loss in Red Hat OpenStack Platform – Part 1 by m4r1k

For Telcos considering OpenStack, one of the major areas of focus can be around network performance. While the performance discussion may often begin with talk of throughput numbers expressed in Million-packets-per-second (Mpps) values across Gigabit-per-second (Gbps) hardware, it really is only the tip of the performance iceberg.
