Comment 12 Mingyu Shi 2020-10-21 12:14:37 UTC
Reproduced with nmstate-0.2.6-6.el8.noarch, reproducer:

nmcli conn add type ovs-bridge conn.interface bridge0
nmcli conn add type ovs-port conn.interface bridge0 master bridge0
nmcli conn add type ovs-interface slave-type ovs-port conn.interface bridge0 master bridge0
# In case that dhcp timeout causes NM deletes ovs-interface, this could be run(or set NM timeout property to unlimited):
nmcli conn modify ovs-slave-bridge0-1 ipv4.method disabled ipv6.method disabled
nmstatectl show

Verified with versions:
