Install and configure controller node in Neutron

[Dalton Cézane]

When restarting the neutron-linuxbridge-agent service, I am facing a problem:
sudo service neutron-linuxbridge-agent status

Same problem for the neutron-dhcp-agent service:

[Oleg Bondarev (obondarev)]

Looks like your config file is missing required config values.
This is an issue of the installer.

Please file a bug to the installer project.

[Oleg Bondarev (obondarev)]

Current issue is: "Tunneling cannot be enabled without the local_ip bound to an interface on the host" - meaning that either "local_ip" missed in config or the node does not have configured "local_ip" on any of it's network interfaces.

[Dalton Cézane (daltoncezane)]

Hello, @Oleg .

As I followed all the instructions from the documentation, the question is: what config value is missing?

Regarding "local_ip", there is no step mentioning such parameter in the tutorial. Thus, if it is really required, I think the documentation must be updated. Could you please tell me where to change this local_ip value?

The /etc/neutron/neutron.conf file does not have such parameter. I just saw this parameter in the /etc/neutron/plugins/ml2/linuxbridge_agent.ini file, in the [vxlan] section. Since I am not planning to use vxlan now, I think this is not required for the basic installation, according to the documentation.

Any suggestion to solve this problem and finish the basic Wallaby Openstack installation is appreciated.

[Oleg Bondarev (obondarev)]

If vxlan is not needed, please make sure 'enable_vxlan' config option is set to False. Thus agent will skip all vxlan validations including local_ip check.

[Oleg Bondarev (obondarev)]

Also please point the place (link) in the documentation that you followed, so that we can add this note there.

[Dalton Cézane (daltoncezane)]

This parameter was already set to false:
enable_vxlan = false

This is the documentation I followed: https://docs.openstack.org/neutron/wallaby/install/controller-install-ubuntu.html

[Oleg Bondarev (obondarev)]

Please share your result ml2_conf.ini and linuxbridge_agent.ini

[Oleg Bondarev (obondarev)]

If enable_vxlan is set to false, local_ip check should simply be skipped according to the code of the LB agent. I'm not sure how the error from bug description could happen then.
LB agent writes debug (or info) logs with all it's config upon start, please verify that enable_vxlan there is set to False. And check failure log again, if it's still the same error.

[Dalton Cézane (daltoncezane)]

Hello, Oleg.

As listed in the previous comment, enable_vxlan = false:
[vxlan]

#
# From neutron.ml2.linuxbridge.agent
#

# Enable VXLAN on the agent. Can be enabled when agent is managed by ml2 plugin
# using linuxbridge mechanism driver (boolean value)
#enable_vxlan = true
enable_vxlan = false

Should I try commenting that line?

[Oleg Bondarev (obondarev)]

Need to make sure this is exact config which agent is running with. It could be seen in agent DEBUG logs (at the beginning)

[Dalton Cézane (daltoncezane)]

Where can I find these DEBUG logs?

The linuxbridge, dhcp and metadata agent logs are:
