Comment 3 Petr Horáček 2022-03-17 12:16:39 UTC

This can be moved to QA once 4.9 errata contains nmstate v0.52.14

Comment 9 Adi Zavalkovsky 2022-04-07 15:03:58 UTC

Verified.

OCP Version - 4.9.28. kubernetes-nmstate-handler v4.9.4-7.

Created veth device on node:
[core@n-adiz49-8s5rp-worker-0-bzxdz ~]$  sudo ip link add 0e12345 type dummy
[core@n-adiz49-8s5rp-worker-0-bzxdz ~]$  sudo ip link set 0e12345 up


NNS Succesfully updated without nmstate-handler pod crashing:
[cnv-qe-jenkins@n-adiz-410-8d2hr-executor ~]$ oc get nns n-adiz-410-8d2hr-worker-0-ff9wp -o yaml
