Comment 1 Fernando F. Mancera 2021-06-16 21:49:13 UTC

I've identified the error. When collecting the information from NM we are not considering duplicated names. Therefore we are overwritting the IP information from br0 (ovs-interface) with br0 (ovs-bridge). This fix is required as it is important for us.

Comment 8 Mingyu Shi 2021-07-20 07:23:26 UTC

Verified with versions:
nmstate-1.1.0-1.el8.noarch
