Created attachment 1593891 [details] NetworkManager journal w/ 'trace' level logging Description of problem: We are using NetworkManager with the OVS plugin to configure a bridge on top of a bonded pair of interfaces. After restarting NetworkManager, only one slave interface is connected. All other ports/bridges/interfaces need to be manually restored with 'nmcli conn up ...' Version-Release number of selected component (if applicable): NetworkManager-ovs-1.12.0-10.el7_6.x86_64 NetworkManager-1.12.0-10.el7_6.x86_64 How reproducible: Always Steps to Reproduce: 1. Install openvswitch and the NetworkManager-ovs plugin 2. Configure bonds and a bridge as below: nmcli conn add type ovs-bridge conn.interface brcnv nmcli conn add type ovs-port conn.interface port0 master brcnv nmcli conn add type ovs-port conn.interface brcnv-port master brcnv nmcli conn add type ovs-interface conn.id brcnv-iface conn.interface brcnv master brcnv-port ipv4.method manual ipv4.address $ip ipv4.gateway $gw ipv4.dns "$dns" nmcli conn add type ovs-port conn.interface bond0 master brcnv ovs-port.bond-mode balance-slb nmcli conn add type ethernet conn.interface $default_device master bond0 nmcli conn add type ethernet conn.interface $secondary_device master bond0 nmcli conn down "System $default_device" nmcli conn mod "System $default_device" connection.autoconnect no 3. systemctl restart NetworkManager Actual results: # nmcli conn NAME UUID TYPE DEVICE ovs-slave-em3 9f8bf683-619d-40de-9174-d6d296733d80 ethernet em3 <green> <...snip / all others 'down' > Expected results: # nmcli conn NAME UUID TYPE DEVICE brcnv-iface cbfe1830-31ff-4a6b-ac52-86f5a1be60e7 ovs-interface brcnv ovs-bridge-brcnv 6c65d0db-e7fe-42b0-8b3c-8be1e5dc508e ovs-bridge brcnv ovs-slave-bond0 f3ec130f-2163-4093-8479-085a0ac815e4 ovs-port bond0 ovs-slave-brcnv-port 1f6e5b0a-5a02-4e06-a85c-c1c55f27e183 ovs-port brcnv-port ovs-slave-em1 b6badd81-f431-48cb-9916-5e1d73b5e1ad ethernet em1 ovs-slave-em3 cb51ba17-8e74-411b-a489-903606da4320 ethernet em3 ovs-slave-port0 aaf0ad18-0ad6-4a66-9cbf-ed6e3c6284c2 ovs-port port0 < ... snip ... > Additional info: Can restore configuration by: nmcli conn up ovs-bridge-brcnv nmcli conn up brcnv-iface nmcli conn up ovs-slave-em1
Let's try on recent 7.7. We've made some changes recently about restarting. I will update this bug in a while.

Proposed fix at: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/merge_requests/215
I see, the duplicate 'brcnv' interface name causes other issues on restart. I didn't realize before because I was using the script attached to the mail where the brcnv ovs interface is commented out. I'm debugging the problem.

Working like a champ now. Huge thanks for the fix!

Hi, the script works for me with NM 1.18.0-6 which is the last version available in RHEL 7.8. Can you please enable trace logging and attach NM logs? Thanks!
