Open vSwitch and OVN 2025 Fall Conference

The Open vSwitch project, a Linux Foundation Collaborative Project, will host its eleventh annual conference focused on Open vSwitch and OVN on November 19 - 20, 2025. The conference will be hybrid. Talks will be presented live during the conference. We are planning to use an online system that allows for text-based discussion, and live Q&A while the talk is happening for virtual attendees. Each talk will have time reserved following the presentation for further discussion via both text, over video and audio, and live with the presenters. Each talk will be given once.

The in-person location for the conference this year will be at the Hotel Botanique (here) in Prague, CZ.

How to propose a Talk

We are seeking long and short ("lightning") talks on topics related to Open vSwitch and OVN. We expect long talks to last 25 minutes with an additional 5 minutes for questions, and short talks to last 10 minutes.

We will also accept proposals for panel discussions and workshops. Please submit them as full talks and make it clear in the description that you are proposing a panel or workshop.

Please submit proposals to ovscon@openvswitch.org by September 8. Proposals should include:

Title and abstract.
Names, email address, and affiliation for each speaker.
Whether you are proposing a full talk or a lightning talk or either one at the committee's discretion.

Speakers will be notified of acceptance by October 1st, 2025.

Speakers should plan to attend the event in person. Travel and accommodations are the responsibility of attendees. The paper review committee may make exceptions for virtual talks, but the preference is for talks to be presented in-person.
