Comment 1 Gris Ge 2020-02-27 06:22:28 UTC

Hi Beniamino,

Does NetworkManager OVS support MTU changes?

Not yet, I'll implement it.

Comment 3 Till Maas 2020-02-27 09:17:54 UTC

Dominik, is this a problem for RHV?

> Dominik, is this a problem for RHV?

Not yet, RHV does not yet use nmstate/NetworkManager for OVS.
I will come back if this bug becomes relevant for RHV.

Comment 6 Till Maas 2020-03-13 07:21:53 UTC

This is reported against nmstate but fixed in NetworkManager - is anything needed for this in Nmstate?

I intend to keep this bug as tracker of nmstate on this issue. Ideally, nothing need to be done by nmstate.

Comment 8 Beniamino Galvani 2020-03-26 20:58:59 UTC

Fixed in NM by:

https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/2da77547bafedd352d5c40f66ccd365c454c30d4

Gris, should I switch component of this bz to NM, or clone it?

I don't think you need bz in NM as NM will rebase in 8.3.
If you want it anyway, clone it.

Comment 10 Beniamino Galvani 2020-04-02 07:21:02 UTC

Okay, I'm going to clone it so that it gets verified by NM QA.

Comment 11 Fernando F. Mancera 2020-04-26 22:09:59 UTC

It would be nice to have an integration test for this in nmstate. Issue: https://github.com/nmstate/nmstate/issues/1048
