Hello,

I'm installing Openstack Antelope with network option 2
( following https://docs.openstack.org/neutron/2023.2/install/compute-install-option2-ubuntu.html)

The interface name of the provider network is eth1, so I put this to bridge_mappings.
The local IP is from the management network.

#------------------------------------------------------
# /etc/neutron/plugins/ml2/openvswitch_agent.ini
#
[DEFAULT]
[agent]
[dhcp]
[network_log]

[ovs]
bridge_mappings = provider:eth1

[securitygroup]
enable_security_group = true
firewall_driver = openvswitch

[vxlan]
local_ip = 192.168.2.71
l2_population = true
#--------------------------------------------------------

However, the neutron log complains that bridger eth1 does not exist. Launching of instances fails

neutron-openvswitch-agent.log:

What are the proper settings?

Any help appreciated
