Comment 8 Mingyu Shi 2020-10-22 09:05:09 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:
nmstate-0.2.10-2.el8_2.noarch

Comment 9 Gris Ge 2020-11-04 13:53:34 UTC 
RHEL 8.3.0 release with nmstate-0.3.4-14.el8_3 containing the fix and RHEL 8.2.1.z is not required any more.
