neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [-] 物理网络提供商的桥接 enp125s0f0 不存在。代理已终止

我的操作系统是 Debian 12。

我部署的openstack集群有两个节点，controller34为控制节点，worker35为工作节点，没有多余的网络节点，我的网络规划是工作节点和网络节点复用，我按照官网文档部署了neutron自服务网络，在控制节点的日志中发现如下错误 这是我的 IP 配置

root@controller34:/home/dky# cat /etc/network/interfaces

        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 192.168.203.11

这是我的错误日志

这是我的配置文件

我在工作节点的日志中没有发现任何错误。

这是我的 IP 配置：

我尝试手动创建网桥，但是没有成功。目前我们还在测试阶段，所以我计划使用单个网络接口来构建外部网络、管理网络、租户网络。

答案1

桥接映射需要桥接，而不是接口，但从文档。但配置选项bridge_mappings非常清楚。我还没有设置 OVN，所以这是针对 OVS 部署的，因为您似乎也需要：

# create provider bridge on control node
ovs-vsctl add-br br-provider

# add port to provider bridge (physnet is probably enp125s0f0 in your case)
ovs-vsctl add-port br-provider {{ physnet }}

# edit /etc/neutron/plugins/ml2/openvswitch_agent.ini

[ovs]
bridge_mappings = provider:br-provider

编辑配置文件后，重新启动neutron-openvswitch-agent.service控制节点上的 ，甚至所有 neutron 服务。然后在计算节点上执行相同操作，因为它也需要桥接映射。如果您打算使用外部（提供商）网络，则需要另一个未配置 IP 的接口。
