问题导读

1.在ovs中如何寻找对应路由？
2..在ovs中如何寻找dhcp server？
3.qr-×××的是指什么网络设备？

下面是如何找到ovs中部分虚拟网络设备，如何在dasboard中找到对应的内容

neutron配置完毕，我们通过ovs

Open Vswitch

网络节点

则是quantum route，通过dasboard

我们打开路由

然后在进入端口：

看到端口qr-bd91f930-92中bd91f930-92取之端口id.

Port "qr-bd91f930-92"
         tag: 1
         Interface "qr-bd91f930-92"
            type: internal
Port "tap19c5765e-d9"
         tag: 1
         Interface "tap19c5765e-d9"
            type: internal
