OpenStack实例为什么无法获取MAC地址?

OpenStack实例为什么无法获取MAC地址?

我们在连接到路由器和交换机的两台服务器主机上设置了 OpenStack 服务器。我们将交换机划分为两个 VLAN:

  • VLAN2:10.2.xx
  • VLAN3:10.3.xx

我们的网络架构包括 VMware 创建的节点:

  • 控制器: 连接至:
  • 放置
  • nova-API
  • 中子服务器
  • 一瞥
  • 基石
  • 煤渣。
  • 五个计算节点:每个节点与 nova-api 和 neutron-server 通信,并连接到 VLAN2 和 VLAN3。

计算节点具有必要的服务,例如openstack-nova-compute并且可以连接到两个 VLAN。

问题

在仪表盘上成功创建实例后,实例运行正常,但无法连接网络,在“网络”->“端口”部分,状态一直是“正在构建”。查询日志发现,neutron-linuxbridge-agent计算节点上无法识别实例网卡。
