RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 5 Gris Ge 2020-10-14 16:52:35 UTC 
To minimize the changed code, this bug only fix the crash of `libnmstate.show()` or `nmstatectl show` on system with
duplicate ovs interface/bridge name. The output will only contains the ovs bridge interface.
CNV does not require nmstate's information on OVS for RHEL 8.3.

And RHEL 8.4 is tracking the effort at bug https://bugzilla.redhat.com/show_bug.cgi?id=1865733
Comment 12 Mingyu Shi 2020-10-21 12:03:46 UTC 
Reproduced with nmstate-0.3.4-12.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-0.3.4-13.el8_3.noarch
