OpenStack 实例部署失败，错误为“无法绑定端口”

我最近一直在努力在我们的 OpenStack 环境上部署实例。每当我尝试从 Horizo​​n 部署新实例时，我都会收到以下错误消息：

Error: Failed to perform requested operation on instance "testinstance", the instance has an error status: Please try again later [Error: Exceeded maximum number of retries. Exceeded max scheduling attempts 3 for instance d0ea4854-e2ab-4f1f-ac11-fc28b8444011. Last exception: Binding failed for port c4a851e7-7ad2-4149-92c7-6116d8965ab2, please check neutron logs for more information.].

我尝试了 ask.openstack.org 和此处提供的多种解决方案，但均无效。错误消息始终保持不变。我还多次查看文档以验证配置文件是否正确。它们是正确的。但我一直收到此错误。以下错误消息可在/var/log/neutron/neutron-server.log在控制器上：

ERROR neutron.plugins.ml2.managers [req-dd158cae-eef9-47c3-9010-ec0f8b16ae59 ee8cee6074064601bc7dc2ce3683faac 716d6d0c0224429eafbf712fc0fe580d - default default] Failed to bind port c4a851e7-7ad2-4149-92c7-6116d8965ab2 on host CoDER-N2 for vnic_type normal using segments [{'id': 'eeaf41d1-b05a-4711-9b5f-86dc0e338391', 'network_type': 'vxlan', 'physical_network': None, 'segmentation_id': 3, 'network_id': '3c92802e-0dc9-4f16-8865-7ee5cfc4d953'}]

以下是控制器上的相关配置文件：

以下是计算节点上的文件： /etc/neutron/neutron.conf

[securitygroup]

firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

我还得到了/var/log/nova/nova-server.log来自此处的计算节点：

2020-11-20 08:28:12.070 332012 ERROR nova.compute.manager [instance: d0ea4854-e2ab-4f1f-ac11-fc28b8444011] nova.exception.PortBindingFailed: Binding failed for port c4a851e7-7ad2-4149-92c7-6116d8965ab2, please check neutron logs for more information.

不幸的是，计算节点上的两个 neutron-logs 都是空的。那里根本没有任何条目。所有服务都已启动并运行。我不知道出了什么问题。我怀疑控制器上的 neutron-server.log 中存在“物理网络：无”这一事实表明存在问题，但我不知道该怎么做。任何帮助都值得感激。

我也遇到过这个问题。你找到解决办法了吗？我猜问题的原因是网络配置错误。
