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 omergi 2019-12-29 16:41:51 UTC 
Description of problem:
When trying to get the mac address of an ovs-interface with nmstate it is shown as (unknown).
It is also not possible to set the mac address of an ovs-interface w/o --no-verify parameter.
(If I use the parameter --no-verify the mac address is set properly)

For example:
I try to set ovs-interface mac address as the address of the nic i connect to the ovs-bridge and set the ipv4.method to auto, such that the ovs-interface will get the same ip address as the nic.


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

How reproducible:
Create an ovs-interface with nmstate, then try to set/view it mac address.

Steps to Reproduce:
1.
get the desired nic mac address, for example eth1

create state mystate.yaml: 
interfaces:
- name: mybr
  type: ovs-bridge
  state: up
  bridge:
    port:
    - name: mybr0
    - name: eth0
- name: mybr0
  type: ovs-interface
  state: up
  mac-address: <eth0 mac address>
  ipv4:
    enabled: true
    dhcp: true


nmstatectl set mystate.yaml
nmstatectl show 
mac address wont show.

Actual results on NetworkManager:
nmcli device show mybr0
result:
GENERAL.HWADDR: (unknown)

Expected results:
eth0 mac address on ovs-interface through 'nmstatectl show' output
eth0 mac address on ovs-interface through 'nmcli c show mybr0' output

Additional info:
log of the upper state:
nmstatectl set mystate.yaml

Comment 1 Gris Ge 2020-02-12 10:53:10 UTC 
nmstate-0.2.3-1 can query OVS mac address and also set MAC address at creation.

But when editing MAC address of existing OVS interface, got failure https://github.com/nmstate/nmstate/issues/777
