I appreciate all the help you have given me, but I think we are going to attempt an OSA deployment. I tested openstack-ansible in a virtual environment and it worked as expected.

The only entries from linuxbridge-agent.log on compute01 seem to correspond with security rule updates on that node, although I'm not sure what its updating since there aren't any bridges on that node anyway.

I've added the output of the requested command. I looked in the neutron logs on the controller and only noticed some 404 entries. I've also included the [neutron] section of the nova.conf file. I noticed that some auth_url entries omit v3 for keystone api. Would this cause a problem?

2019-02-13 23:16:26 -0500 回答问题 What interface do I assign physical_interface_mappings for provider network?

I believe that if you are not using provider networks for your instances, you do not need to specify the physical_interface_mappings value on compute nodes. You would only need this if you wished to allow the provisioning of instances with direct access to the provider network (eg trusted instances). More likely, your instances would access the provider network through the network node, which can be set to route tenant traffic if you configure it to do so. Another thing to note is that no ip address needs to be assigned to interfaces designated for access to provider networks.

Take what I say with a grain of salt, as I am new to OpenStack. Someone please correct me if I am wrong.

After attempting to launch an initial cirros image on a self-service network, I am receiving the following error:

Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.

2019-02-13 17:23:28 -0500 评论问题 What is necessary to make Neutron changes?

I rebooted the controller and compute nodes, stopped the firewalls, removed the provider and project networks, recreated them, and attempted to fire up a new instance. I keep getting this error: <class 'neutronclient.common.exceptions.NetworkNotFoundClient'> (HTTP 500)

2019-02-13 04:33:16 -0500 问了问题 What is necessary to make Neutron changes?

I recently attempted to configure Neutron for the first time, but of course made some errors in my configs (linuxbridge_agent.ini). I have corrected the errors (as far as I know) and rebooted all nodes. Are there any other steps that need to occur for changes to take place?

2019-02-06 01:02:00 -0500 评论回答 What interface do I assign physical_interface_mappings for provider network?

My goal is to allow tenants to create and manage their own isolated networks, so I'm assuming I need to enable self-service networks to accomplish this.

2019-02-06 01:02:00 -0500 评论问题 What interface do I assign physical_interface_mappings for provider network?

I tried as you said. Neutron didn't complain and I was able to complete installation. When I finish configuration, I will post an update about whether tenant networks were able to route out to the provider network

2019-02-04 21:31:54 -0500 问了问题 What interface do I assign physical_interface_mappings for provider network?

I am building a small cluster using the Rocky installation tutorial, however, my cluster design is a bit different. The following is how I have it connected:

https://i.imgur.com/6fE0IER.jpg (OpenStack PoC Cluster)

On the controller, I set the physical_interface_mappings = provider:enp4s0, which is the connection to the provider network in the diagram above. I am currently configuring Neutron on a compute node. Every source seems to say that when configuring Neutron on a compute node, you should set physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME. That would seem to imply that the compute node should be connected to the provider network directly. However, much of what I have read implies that North-South traffic is routed out to the Provider network through the network node (which is also the controller in my setup).

Am I confusing the network topology? If not, what interface should be assigned to physical_interface_mappings?
