Hi guys.

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.
