Customer wants update OpenvSwitch 1.10.1 to 2.3

We have .dep packages OpenvSwitch 2.3.1 but we don't have openvswitch-datapath-lts-saucy-dkms for this version
Please build this module for customer

Alexander:

First, the bug as it is now contains just question rather than problem statement or a request. Please update the description to be more clear.

Second, bulding custom DKMS and/or updating OpenvSwitch is definitely not responsibility of MOS Sustaining team, probably MOS Linux or Services - depending on what exactly you need.

Third, I think Fuel for OpenStack 5.1-updates milestone is not correct here as this issue is not related to maintenance update of Fuel 5.1.

Please update the bug and proceed accordingly, thanks!

OpenVSwitch 2.3.1 that was merged to 6.1 contains new dkms module:
https://review.fuel-infra.org/#/c/4433/3/debian/openvswitch-datapath-source.install

dkms itself does not depend on kernel version, so there is no problem using new module with old kernel (dkms subsystem will compile the module upon installation).

[Michael Semenov (msemenov)]

OVS 2.3.1 merged into MOS 6.1, so fix committed.

[Michael Semenov (msemenov)]

Won't fix for older versions. OVS will not be updated for them, but there is a link in the bug https://bugs.launchpad.net/mos/+bug/1425983/comments/2 describes where to find DKMS kernel module for OVS 2.3. If customer wants to have OVS 2.3.1 on the old builds, he/she should ask Support team for custom MOS ISO. Alexander Mogylchenko can help with it.

Dear Team,

As we already know OVS is an important part of fuel especially if you have to deal with lacp/bonding stuff. The version 1.10.x that comes with fuel 5.1.x is little old and has some well known problems.

I think that openvswitch is a fundamental part of fuel and has a great impact on user experience. That is the reason that I think
it would be nice to have new OVS packages backported to the fuel-repository for 5.1.x versions.
I assume there would be plenty of installations with 5.1.x releases already installed out there that would benefit from this upgrade.

thank you
