[neutron][openvswitch][antelope] Bridge eth1 for physical network provider does not exist
Hello, I'm installing Openstack Antelope with network option 2 ( following https://docs.openstack.org/neutron/2023.2/install/compute-install-option2-ub...) The interface name of the provider network is eth1, so I put this to bridge_mappings.

Hi, You need to create bridge (e.g. br-ex), add your eth1 to that bridge and put name of the bridge in the bridge_mapping. Dnia poniedziałek, 23 października 2023 21:44:43 CEST ddorra@t-online.de pisze:

Hi,
many thanks for the hint! I'm wondering how the original instructions can work at all where the interface is added to the bridge mapping (https://docs.openstack.org/neutron/2023.2/install/compute-install-option2-ub...)
It can't. This was mistake in our docs and I just proposed fix for it https://review.opendev.org/c/openstack/neutron/+/899376
I assume this needs to be done on both the controller and the compute node?
Yes.
However, now the error says "failed to bind port..."...
For the reason of failed bind of the port You need to check neutron-server logs. This is important line: 74d f94c5c69fe0e4456a19426da0877431f - default default] Failed to bind port 64d76a96-e739-4680-b367-e46f2fd46639 on host loscompute1 for vnic_type normal using segments [{'id': 'ce394d12-4255-4298-8332-5f39fbea7444', 'network_type': 'vxlan', 'physical_network': None, 'segmentation_id': 805, 'network_id': '32f53edc-a394-419f-a438-a664183ee618'}] From that it seems that You are using vxlan network, not provider network. So bridge_mappings aren't needed for You at all. But You need to make sure that vxlan tunnel_type is enabled in the agent's config. Please check https://docs.openstack.org/neutron/2023.2/admin/deploy-ovs-selfservice.html for more details.

Hi,
You need to create bridge (e.g. br-ex), add your eth1 to that bridge and put name of the bridge in the bridge_mapping.

Hi, not sure if that will fix anything, but this is different in my environments:
[vxlan] local_ip = 192.168.2.70
I don't have the [vxlan] section but instead this in the openvswitch_agent.ini on the compute nodes: ---snip--- [agent] tunnel_types = vxlan l2_population = True [ovs] local_ip = <ip> bridge_mappings = provider:br-provider of_inactivity_probe = 30 [securitygroup] firewall_driver = iptables_hybrid ---snip--- and this on the control nodes (basically the same except for the IP): ---snip--- [ovs] bridge_mappings = provider:br-provider local_ip = <ip> of_inactivity_probe = 30 [agent] tunnel_types = vxlan l2_population = True [securitygroup] firewall_driver = iptables_hybrid ---snip--- Maybe this helps. Zitat von ddorra@t-online.de:
Hi,
many thanks for the hint! I'm wondering how the original instructions can work at all where the interface is added to the bridge mapping (https://docs.openstack.org/neutron/2023.2/install/compute-install-option2-ub...)
I assume this needs to be done on both the controller and the compute node?
However, now the error says "failed to bind port..."...

I recently went through the current documentation to install a single node OpenStack manually and fixed a few doc bugs. The wrong options pointed out by Eugen would be fixed once https://review.opendev.org/c/openstack/neutron/+/899227 is merged. It's probably worth checking. On 10/26/23 22:00, Eugen Block wrote:
Hi,
not sure if that will fix anything, but this is different in my environments:
[vxlan] local_ip = 192.168.2.70
I don't have the [vxlan] section but instead this in the openvswitch_agent.ini on the compute nodes:
---snip--- [agent] tunnel_types = vxlan l2_population = True
[ovs] local_ip = <ip> bridge_mappings = provider:br-provider
of_inactivity_probe = 30
[securitygroup] firewall_driver = iptables_hybrid ---snip---
and this on the control nodes (basically the same except for the IP):
---snip--- [ovs] bridge_mappings = provider:br-provider local_ip = <ip>
of_inactivity_probe = 30
[agent] tunnel_types = vxlan l2_population = True
[securitygroup] firewall_driver = iptables_hybrid ---snip---
Maybe this helps.
Zitat von ddorra@t-online.de:
Hi,
many thanks for the hint! I'm wondering how the original instructions can work at all where the interface is added to the bridge mapping (https://docs.openstack.org/neutron/2023.2/install/compute-install-option2-ub...)
I assume this needs to be done on both the controller and the compute node?
However, now the error says "failed to bind port..."...

Hi,
You need to create bridge (e.g. br-ex), add your eth1 to that bridge and put name of the bridge in the bridge_mapping.

Hello,
I'm installing Openstack Antelope with network option 2 ( following https://docs.openstack.org/neutron/2023.2/install/compute-install-option2-ub...)
The interface name of the provider network is eth1, so I put this to bridge_mappings. The local IP is from the management network.
