 However there is workaround is remove the existing `ovs-if-br-ex` by  `nmcli connection delete ovs-if-br-ex` can fix this issue. 

    4.17.0-0.nightly-2024-09-07-151850

    not always

    1.  Create many bond interface by nmstate nncp
    2. reboot worker
    3.
    

    ovs-configuration service cannot be started up 

     ovs-configuration service should be started without any issue

  Not sure if these bond interface affected this issue. 
  However there is workaround is remove the existing `ovs-if-br-ex` by
  `nmcli connection delete ovs-if-br-ex` can fix this issue.
