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..."...
What I did:

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.
