I'm still wondering if the issue is Kconfig-related (plus possibly bad interaction with vng). I don't see the OVS knob enabled in the self- tests config. If it's implied by some other knob, and ends-up being selected as a module, vng could stumble upon loading the module at runtime, especially on incremental build (at least I experience that problem locally). I'm not even sure if the KCI is building incrementally or not, so all the above could is quite a wild guess.
In any case I think adding the explicit CONFIG_OPENVSWITCH=y the selftest config would make the scenario more well defined.
That is in 7/7 - but there was a collision with a netfilter knob getting turned on. I can repost it as-is (just after rebasing) if you think that is the only issue.
Sorry for not checking it earlier, looks like the runner was missing pyroute:
# python3 ./tools/testing/selftests/net/openvswitch/ovs-dpctl.py Need to install the python pyroute2 package >= 0.6.
I guess run_cmd counter-productively eats the stderr output ? :(
Yes, otherwise it's rather noisy, but you can run the thing with VERBOSE=1, see also 56490b623aa0 ("selftests: Add debugging options to pmtu.sh").
Before that change, we didn't eat standard error, but in the general case I guess it's quite an improvement.
