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.

Description Quique Llorente 2021-05-25 07:36:03 UTC 
Description of problem:

At an openshift 4.8 cluster with OVNKubernetes after creating a veth it's impossible to add the peer to the br-ex bridge, only the veth is added and the rest of interfaces are deleted.


Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. git clone https://github.com/nmstate/nmstate && cd nmstate
2. export KUBEVIRT_PROVIDER=external  
3. export KUBECONFIG=[path to the kubeconfig]
4. ./automation.sh --k8s --centos-stream --test-type=none --debug-shell
5. [different shell] oc cp -n nmstate state.yaml conformance:/tmp/
6. nmstatectl set /tmp/state.yaml

Actual results:
name: br-ex
type: ovs-bridge
state: up
bridge:
  options:
    fail-mode: ''
    mcast-snooping-enable: false
    rstp: false
    stp: false
  port:
  - name: ovn-veth
lldp:
  enabled: false


Expected results:
name: br-ex
type: ovs-bridge
state: up
bridge:
  options:
    fail-mode: ''
    mcast-snooping-enable: false
    rstp: false
    stp: false
  port:
  - name: br-ex
  - name: enp5s0
  - name: ovn-veth
lldp:
  enabled: false

Comment 4 Quique Llorente 2021-05-25 13:29:43 UTC 
Add enp5s0 to the desired state improves things a little since it appears as part of the ports, but if I add the br-ex ovs-interface br-ex ovs-bridge breaks.

Hi Quique, thanks for this report. I am looking into this.
