ETSI's Centre for Testing and Interoperability and the OSM community organized the 7th OSM Hackfest on 9-13 September 2019.The event was hosted by University of Patras in Patras, Greece), co-located with the OSM Mid-Release#7 meeting.


This OSM Hackfest offered a great opportunity to share and learn with OSM developers and module leaders, and explore opportunities for synergies and collaboration.

This OSM Hackfest allowed new users to get familiar with OSM Release SIX and exercise all the main functionalities, from basic operations (installation, setup, common operations, etc.) to most advanced capabilities, such as 5G network slicing with a big focus on VNF on-boarding activities covering Day 0/1/2 operations.

In addition, experienced users and developers had the opportunity to hack into OSM, build complex examples, fine-tune, test and demonstrate Release SEVEN and experimental features on the OSM Remote Labs network.

Objectives - OSM Hackfest participants learnt to:

  • Install OSM and run some examples
  • Get familiar with OSM's GUI and CLI
  • Create own VNF and NS descriptors and build packages
  • Model and deploy NS/VNF with EPA capabilities
  • Model dynamic Life Cycle Management operations with Day-1 and Day-2 actions
  • Model 5G Network Slices and complex NS with PNFs
  • Perform basic troubleshooting
  • Configure Fault and Performance management and close-loop operations
  • Modify and experiment with OSM source code
  • Build complex examples and run own experimental testing

OSM & 5G Verticals

Wednesday afternoon was dedicated to projects and initiatives leveraging OSM to accelerate the development, standardization, testing and / or deployment of 5G services for different verticals: Automotive, Smart Cities, Smart Manufacturing, Media, ... Participants interested in presenting their work had to reach out to

 Remote Labs

During OSM Hackfests participants build and try real examples of OSM interaction with different VIMs and NFV infrastructures that are kindly made available by our community members at ETSI or through the OSM Remote Labs network.

Who should attend:

  • VNF vendors, who want to onboard their VNF in OSM following best practices
  • System Integrators, who want to get started with OSM
  • Service providers, who want to get first hand operational experience with OSM
  • Academia and Universities, who are using or considering OSM as platform for their research activities in networking
  • Experimented developers and users that want to share and test with the community


  • Seats are limited, registration is mandatory
  • Participants are expected to have user-level knowledge of Linux and be familiar with NFV and SDN concepts
  • Laptop / VM in laptop
    • Linux installed (preferred, Ubuntu 16.04)
    • RECOMMENDED: 2 CPUs, 8 GB RAM, 20GB disk
  • It is highly recommended that you download and install OSM Rel SIX before the hackfest.
