问题描述
我使用此指南[OpenStack Charms部署指南]执行了群集节点安装.( https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-maas.html )，其中类型网络是一个扁平网络，使用的组件是:
I performed a cluster node installation using this guide [OpenStack Charms Deployment Guide].(https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-maas.html), where the type of network is a Flat network and the components used are:
- 马斯
- Juju
- Openstack
我的实验室由以下设备组成:

在我的实验室中，Openstack的节点具有两个eth接口，第一个(eno2)用作浮动IP的单个外部网络，然后另一个(eno3)专用于私有网络.
On my lab, the nodes for Openstack present two eth interface, the first one (eno2) the single external network used as floating IP, then the other one (eno3) for the private network.
我在Juju gui上
On Juju gui I've that:
neutron-gateway:
bridge-mappings: physnet1:br-ex
data-port: br-ex:eno2
neutron-api:
flat-network-providers: physnet1
我已打开此帖子 https://ask.openstack.org/en/question/119783/no-route-to-instance-ssh-and-ping-no-route-to-host/解决与实例之间的Ping和Ssh连接有关的问题，但在同一检查期间，我在中子网关上看到了此问题:
I've opened this post https://ask.openstack.org/en/question/119783/no-route-to-instance-ssh-and-ping-no-route-to-host/ to resolve the problem about the Ping and Ssh connection to my instance, but during same check I've seen this issue on neutron-gateway:
error: "could not add network device eno2 to ofproto (Device or resource busy)"
也许这是我第一个问题的原因，但是我不知道如何解决.
Maybe that is the cause of my first issue, but I don't understand how I can fix it.

请提出任何建议.我仍然无法解决问题.谢谢.
Any suggestions please. I am still unable to solve the problem. Thanks.
推荐答案
更新26/03/19:
我在Juju gui上
On Juju gui I've that:
neutron-gateway:
bridge-mappings: physnet1:br-ex
data-port: br-ex:eno2
neutron-api:
flat-network-providers: physnet1
在部署Openstack之前，我已将数据端口从br-ex:eno2更改为br-ex:eno3
Before to make the deploy of Openstack I've changed data-port from br-ex:eno2 to br-ex:eno3
neutron-gateway:
bridge-mappings: physnet1:br-ex
data-port: br-ex:eno3
有关eno2的问题已解决，但仍然可以ping通实例.
The issue on eno2 is been resolved but the ping to instance is still present.
这篇关于打开堆栈中子网关-错误:“无法将网络设备eno2添加到ofproto(设备或资源繁忙)"的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
