I have followed all steps about openstack newton on ubuntu 16.04 and now I am not able to launch the "provider" instance.

I get "BUILD" on dashboard.

Here is the instruction that I follow: (link text)

Any idea?

Thanks, Costas

Hi Costas, Dashboard doesn't give too much fault information. You need to start checking log files. The link in your question explain how to create instance via CLI. If you use CLI, you can add "--debug" parameter in to the command to see what is going wrong while your command is running.

Hello Senol,

Could you see below the output of ifconfig after my try to create the instance and the --debug parameter.

Also I am not able to ping on step 4 from the instructions below. (

Thanks, Costas

What compute logs say? Before the creation command;

  • On the controller node; tail -f /var/log/nova/nova-api.log /var/log/nova/nova-conductor.log /var/log/nova/nova-scheduler.log |grep ERROR

  • On the compute nodes; tail -f /var/log/nova/nova-compute.log |grep ERROR

Senol you are able to see the output of all.

keep in mind that the specific output is after the creation command. I will send you and the before creation command

The error that you see is related to the Placement service, which in your case is missing. However, this service is optional in Newton, so you can disable it if you want to save some headache by now. Take a look if in nova.conf you have anything uncommented under [placement].

Seems there is a confusion needs some corrections. On the Controller node "nova-api.log, nova-scheduler.log,nova-conductor.log " and on the Compute node, "nova-compute.log"

and, if the instance still remains in "BUILD" state, can you post the result of

nova show provider-instance
Senol Erdogan gravatar imageSenol Erdogan ( 2017-09-18 03:03:29 -0500 )edit

On the [placement] I have uncommented the below on controller and compute node:

os_region_name = openstack

Is it wrong?

Costas gravatar imageCostas ( 2017-09-18 12:39:15 -0500 )edit

I am not able to post the result from nova show provider-instance according to limit characters. Could you download the log files through wetranfer?

Costas gravatar imageCostas ( 2017-09-18 12:58:48 -0500 )edit

Regarding the placement, have you installed and configured nova-placement? Because if not, the presence of uncommented lines in that section triggers Nova to use the placement. Check it out carefully and try by commenting that and restarting your services.

unusualfor gravatar imageunusualfor ( 2017-09-18 14:01:56 -0500 )edit

However, from the logs it seems that you are running on Ocata. Could you try to assure that all your components have been installed from the correct newton repo?

unusualfor gravatar imageunusualfor ( 2017-09-18 14:03:05 -0500 )edit

I have no configured the nova-placement service, this is the line on nova.conf on section placement. Regarding the second. How I check if all the components are from newtron repository? Maybe I have something wrong :(

It is crucial for me to find the error ..

Costas gravatar imageCostas ( 2017-09-18 14:08:35 -0500 )edit

If I try to uninstall "nova-api nova-conductor nova-consoleauth \ nova-novncproxy nova-scheduler" with remove nove db & nova_api db and reinstall it again is it a good idea? Or my system will be crashed?

Costas gravatar imageCostas ( 2017-09-18 15:21:53 -0500 )edit

And reconfigure networking as well..???

Could you check please if all that attached are right?

Thanks for your efforts.

Check it with "nova-manage version". I told you about Ocata because of: 1) the warning, 2) the placement problem that it seems you are facing :) try it out

unusualfor gravatar imageunusualfor ( 2017-09-19 16:12:01 -0500 )edit

nova-manage version 15.0.6

Costas gravatar imageCostas ( 2017-09-19 16:41:00 -0500 )edit

I tried to comment out the parameter of placement on both controller & compute and after that I wasn't able to see the system information on dashboard.

Costas gravatar imageCostas ( 2017-09-19 16:43:05 -0500 )edit

If I will uninstall nova, delete the db and reinstall it it a good idea or not? Also I would like to inform when I ran the "# su -s /bin/sh -c "nova-manage db sync" nova" I get the "warning:cell0 mapping not found - not syncing cell0".
