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"

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.

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.
That is quite bad I'd say as this is important.
I did add my comments to that bug report.
regards, L
Thanks,
Ales
