I've been meaning to do something like this for about 3 years and finally got around to it. It's a video series in which I go over a number of common Git and Gerrit activities for doing OpenStack development. As I mention in the intro, this isn't ... [More] intended to be Baby's First Git/OpenStack Tutorial (although I do go over some pretty basic stuff) because there are other resources for that. What it is intended to cover is the stuff I periodically see questions about from other OpenStack developers. I'm hoping it will be helpful for new and even more experienced developers. Of course, feedback is always welcome. If you know a better way to do something I demo in the videos then I would love to hear about it. Anyway, here's the YouTube playlist of all the videos I've recorded so far. Git and Gerrit Demo Videos. I may make more in the future (especially if I end up seeing a lot of questions about a certain topic), and of course will add them to the playlist if I do.

OpenStack Interop ChallengedfinebergOctober 17, 2016The goal is to prove that different OpenStack clouds can work seamlessly with each other.  From a report by Luz Cazares, Intel Open Source Technology Center   The OpenStack Innovation Center (OSIC) ... [More] proudly participates in the interoperability challenge, originally proposed by IBM via the Interop Working Group (aka Defcore).  The goal is to prove OpenStack interoperability—that is, different OpenStack clouds can work seamlessly with each other.    First, participants run Defcore guidelines via RefStack tools. Second, participants run workloads on top of OpenStack production clouds—without any modification or special tweaks.   Two common workloads (lampstack and dockerswarm) run on participant’s clouds.  Both workloads use Ansible as the underlying IT automation engine.    To take part in the challenge, OSIC made a project available on Cloud1, which includes all needed resources, and where we executed all the test cases.  The quality engineering team successfully tested Defcore guidelines 2016.01 and 2016.08.  The lampstack and dockerswarm workloads also ran successfully, with no major incidents.     However, the team faced challenges when setting up the deployer VM.  As a result, we provided shell scripts to handle the installation of deployer VM pre-requisites.  To get the shell scripts and more, visit our repo on github.   Going to the OpenStack Summit in Barcelona, 25-28 Oct. 2016?   Stop by the OSIC booth for a demo, and look for the Interop (DefCore) Working Group Work Session on Tue 25 Oct., 2:15pm-2:55pm.  Also check out the presentation, Beyond RefStack: The Interop Challenge, Thu 27 Oct. 11:00am-11:40am.   [Less]

Scalability and integration of VMware Integrated OpenStack (VIO) dfinebergOctober 17, 2016The team tested the performance and scalability of provisioning the full-stack environment, from hardware configuration to VMware and OpenStack software ... [More] installation.   Adapted from a report in development by Intel OTC’s Dr. Yih Leong Sun, and VMware’s Binbin Zhao, Fred Vong, and Arvind Soni   In July 2016, VMware collaborated with the Intel Open Source Technology Center (OTC) to analyze the performance of VMware Integrated OpenStack (VIO).  The OpenStack Innovation Center (OSIC provided a 132-node cluster as the testing environment for a three-week period.  The team tested the performance and scalability of provisioning the full-stack environment, from hardware configuration to VMware and OpenStack software installation.   The scale test environment included 120 compute nodes. The entire scale testing environment took a week to set up. This included a complete installation of virtualization products, hypervisor, SDN, and converged storage, as well as setup of OpenStack services (all deployed as virtual machines).   Each server included HP Integrated Lights-Out (iLO) remote server administration, used for retrieving mac addresses, mounting ISO images, setting boot devices, resetting power, and other functions.   The team used two different performance tools to simulate the workload and measure the results, a fog.io based orchestration tool and OpenStack Rally.   Key Findings The OpenStack control plane successfully handled the creation of 10,000 VMs across 120 servers. For all OpenStack services, vital statistics of CPU and memory remained stable and healthy as the workloads increased. However, we didn’t get a chance to measure the API response time for the operations involved. As the number of total objects increased, we saw degradation in the response time for completing OpenStack operations, such as VM creation. Depending on the infrastructure orchestration tool, we saw a jump in failure rates when concurrency was increased beyond a certain threshold. Keystone and Neutron interaction was identified as the cause for failures, although the exact defect is still under investigation. Default Nova scheduler results in uniform distribution of workloads across all the nodes and uniform utilization of underlying resources.      The team plans to expand the experiment to a larger compute cluster with 256 nodes, and they will add measurements of the overall API response time for OpenStack services, in addition to the performance of message queuing and databases.   “It all went well, for the first phase of testing,” said Intel’s Yih Leong Sun, “The results are helping us fine-tune things for the next 256-node phase, and ultimately to our goal of more than 500 nodes.”   For more information, read the full report, and visit this link for more information on VMware Integrated OpenStack (VIO).
