Using signed dbosoft OVS / OVN build for Windows

[fw2568]

Hello,
I noticed that you don't distribute a signed driver for OVS. We maintain an OVS driver (https://github.com/dbosoft/ovs), a Windows build for OVN (https://github.com/dbosoft/ovn), and a management library for OVN (https://github.com/dbosoft/dotnet-ovn) for https://www.eryph.io, which uses OVN for overlay network support. Installation of OVS and initial setup was one of the pain point in eryph, so we have no installer but a full driver management which is currently part of eryph-zero: https://github.com/eryph-org/eryph/blob/main/src/apps/src/Eryph-zero/Startup/EnsureHyperVAndOvsStartupHandler.cs

If you find this helpful, I can offer to include our signed driver package in Antrea. Let me know if you're interested.

Best Regards,
Frank

Thanks for the note, and sorry for the delay, I was on vacation at that time.

I think it would be great for users to have the option to use an already signed driver when installing Antrea on Windows. 2 questions:

• do you make any notable change to the Windows datapath code in your OVS fork?
• do you have an URL that can be used to download the driver files? If yes, we should be able to open a test PR and run our existing test pipelines using your driver, for validation.

Hi, yes - now I was on holiday:-) We made some changes but most of them only for hotfixes - some made it already upstream - and separating the driver IDs from OVS build drivers, so we do not conflict with it. Release is currently bundled with eryph, but that something we can change.
I will check for details next days.

Sorry for the long silence, but we received some signals from the OVS team that they were planning to remove Windows support, which put the future of our fork and the eryph network stack on hold. As you probably know, the decision was made to remove Windows from both OVS and OVN and it is already gone in latest builds.

We have decided to maintain it ourselves and are currently investigating how to do so. For now, we have a working OVN/OVS on 26.03. An unsigned build can be downloaded here: https://github.com/dbosoft/ovn/actions/runs/26625239984. Signing will follow soon.

What are your plans for OVS on windows?

Is that a recent decision? Is there any link that you can share with us about this?

I had also a link to the OVNCon where it was decided, but have not found it just now.

Code is also already gone:
