I have both(and probably other relevant components pulled in) NetworkManager and openvswitch2.11 from ovirt-4.4-copr and cannot confirm if the problem is exclusive to ovirt-4 but I thought this here is where I should start a quest for help. I use NM to set up OVS' bridges and pretty straightforward setup I believe, yet each time after system reboot one (always the same) interface fails to start and stays in a weir state, actually it gets duplicated. ovs0-int-10.3.3 d9c9268f-408c-4035-9684-97e4eaf92e18  ovs-interface ovs0-int33 (colored yellow) ovs0-int-10.3.3 d9c9268f-408c-4035-9684-97e4eaf92e18  ovs-interface ovs0-int33 (colored red) whereas the rest of the bridge: ovs0-int-10.1.1 be5e79e7-2e4e-47ed-97d0-270c76e43b9a  ovs-interface ovs0-int11 ovs0 9cf72215-eebc-4f7c-9466-b697f09e1bda  ovs-bridge ovsbr0 ovs0-port-11 1577414e-7eeb-41bc-a66f-7b7b596285d0  ovs-port ovs0-port11 ovs0-port-33 5465d3c5-9a0c-4f78-89c0-de94b0294d0e  ovs-port ovs0-port33 ovs0-port9 b9c2b7cd-897e-4726-8fc7-e2f7c7aab067  ovs-port ovs0-port9 ovs0-port9-physical 14fb0b0e-f7bb-4248-9295-34f561058f4d  ethernet enp7s0f1np1 ovsbr0-libvirt0-int f217cd6c-976b-4002-b191-9f15271602cd  ovs-interface ovsbr0 ovsbr0-libvirt0-port 7c2d30bd-0019-4cdb-af05-3df666005261  ovs-port ovsbr0 And then only another reboot with either: a) deletion of the interface prior to reboot and after the reboot creation anew b) removal of /etc/openvswitch/conf.db prior to reboot. When all is good and whole bridge is up & running then bridge looks like this: 004e89ac-4c45-4a33-9347-c1d343889ceb     Bridge "ovsbr0"         Port "ovs0-port11"             tag: 11             Interface "ovs0-int11"                 type: internal         Port "ovsbr0"             Interface "ovsbr0"                 type: internal         Port "ovs0-port9"             Interface "enp9s0f3"                 type: system         Port "vnet0"             tag: 33             Interface "vnet0"         Port "ovs0-port33"             tag: 33             Interface "ovs0-int33"                 type: internal     ovs_version: "2.11.0" journal does not tells much, at least not by default .... device (ovs0-int33): Activation: starting connection 'ovs0-int-10.3.3' (d9c9268f-408c-4035-9684-97e4eaf92e18) .... nmcli shows: ... GENERAL.STATE:                          activating ... and also: ... GENERAL.STATE:                          deactivating ... at the same time as the interface is duplicated so are GENERAL entries. I'm on Centos8(no Stream) and with kernel-ml. It feels (I have no lab where I could fiddle more) that this should reproduce. I have a second system with slightly different hardware and this same problem occurs. Any suggestions on how to troubleshoot and/or solve it I'd greatly appreciate. many thanks, L. _______________________________________________ Users mailing list -- users(a)ovirt.org <mailto:users@ovirt.org> To unsubscribe send an email to users-leave(a)ovirt.org <mailto:users-leave@ovirt.org> Privacy Statement: https://www.ovirt.org/privacy-policy.html <https://www.ovirt.org/privacy-policy.html> oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ <https://www.ovirt.org/community/about/community-guidelines/> List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/4UULTUMEOZV... <https://lists.ovirt.org/archives/list/users@ovirt.org/message/4UULTUMEOZV... Hi, that seems like you are hitting https://bugzilla.redhat.com/1891437 <https://bugzilla.redhat.com/1891437>;. In that case we unfortunately don't know the root cause yet and don't have any possible workarounds. It might be helpful if you can also share some of your details on that bug.
