Normally, logs are saved in /var/log/, but by far we don’t have clue what went wrong. Assume the host here you mentioned means the active controller, you can check the alarms first by: controller-0:~$ source /etc/nova/openrc [wrsroot@controller-0 ~(keystone_admin)]$ fm alarm-list From: Jaewook Oh <jwoh95@dcn.ssu.ac.kr> Date: Tuesday, 22 January 2019 at 3:46 PM To: "Hu, Yong" <yong.hu@intel.com> Cc: "starlingx-discuss@lists.starlingx.io" <starlingx-discuss@lists.starlingx.io> Subject: Re: [Starlingx-discuss] After deployment finished, cannot create public flat network 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?

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.

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!
