Hi Jaewook:

      You can try http://10.10.10.2/admin/providernets/  to open , please change 10.10.10.2 to your oam ip.

     Then you can define flat provider networks.



   About log,  you can try run command ‘collect’ to collect all logs , configs .



Thanks.

BR
Austin Sun.

Hi  Jaewook,
I had a similar issue after deploying an AIO Simplex StarlingX.
I had to re-define the host-if on the controller-0 first and then create the related providernet.

Here an example. Hope it helps.

Besides, you can't create it via dashboard,. I managed to do it only via command. So something like:

neutron providernet-create public_flat --type=flat
system host-if-list -a controller-0
system host-if-modify -c data controller-0 eno6 -p public_flat
system host-if-list -a controller-0
openstack network create provider_flat --provider-physical-network public_flat --provider-network-type flat --share --external

which will create something like:
[wrsroot at controller-0 ~(keystone_admin)]$ openstack network show provider_flat

Hello Hu, Yong,
Thanks for the advice.

On my dashboard, "Danger: An error occurred. Please try again later."
Above error message appears, and I cannot open network creation panel.

And also I'm now trying to see log in the host, but I cannot find it. Is the log disabled by default for StarlingX?

BR,
Jaewook.

Hey,
Pls share the error messages you saw on Horizon.

As to your question: “Is there any way to create flat network on StarlingX openstack platform?”
Yes, you can refer to CMD:
$ openstack help providernet create
$ openstack help network create

Of course, since you had error on Horizon, there should be something wrong.
So, let’s figure out why it failed first.

Subject: [Starlingx-discuss] After deployment finished, cannot create public flat network

Hello,
this is Jaewook Oh from IISTRC.

I installed StarlingX on a server, and now I'm trying to create "flat network" for public.
However I couldn't find the way to make the network.
I found "managed_flat", "managed_vlan", and "managed_vxlan" options in '/etc/neutron/plugins/ml2/ml2_conf.ini' file.

When I install some OpenStack platform, I usually used devstack, and with devstack I could choose 'flat' option.

Is there any way to create flat network on StarlingX openstack platform?

And also network creation keeps failing on horizon dashboard. I had to use OpenStack CLI. Is it also a bug?

Thanks in advance for any help!

Best Regards,
Jaewook.
