我有点菜鸟，我正在尝试在3台Debian Machine上安装OpenStack（XENA），分别为Node1，Node2和Node3。
默认情况下，所有这些机器都有固定的IP地址（在DHCP服务器中）：
node1: 172.0.16.250
node2: 172.0.16.251
node3: 172.0.16.252
---
gateway: 172.0.16.2
mask: 255.240.0.0
---
dhcp server start->finish: 172.0.16.10 -> 172.0.16.249
我的目标是仅测试OpenStack。我想在Node1上安装Instra，计算和存储在Node2＆amp; Node3。
遵循安装过程我节点的配置示例。
重新启动节点时，我不再与Internet连接，也不再与本地网络连接。
我了解我做错了什么，我想从这些机器上与Internet联系，并从LAN的任何时候与它们联系，以便我可以安装Ansible。
我关注的步骤： https：// docs。 OpenStack.org/project-deploy-guide/openstack-ansible/latest/deploymenthost.html
I am a bit of a noob, and I am trying to install openstack (xena) on 3 debian machine, respectively named node1, node2 and node3.
By default, all those machines have a fixed ip address (in the dhcp server):
node1: 172.0.16.250
node2: 172.0.16.251
node3: 172.0.16.252
---
gateway: 172.0.16.2
mask: 255.240.0.0
---
dhcp server start->finish: 172.0.16.10 -> 172.0.16.249
My goal is to simply test openstack. I want to install the infra on node1, compute and storage on node2 & node3.
While following the installation procedure here, I have to add virtual network. The 3 computers only have 1 ethernet connection each. I use this configuration example for my nodes.
When restarting the node, I do not have any connection to internet anymore, nor to the local network.
I understand that I am doing something wrong, and I would like to contact internet from these machines, and contact them from any point in my LAN, so I can install openstack with ansible.
The steps I am following : https://docs.openstack.org/project-deploy-guide/openstack-ansible/latest/deploymenthost.html

如果您像VirtualBox一样在虚拟机构上进行Ruun，请尝试添加专用的NAT模式接口以供Internet访问。以及您的桥梁的多个接口，例如br-mgmt br-vxlan和..
If you are ruuning on Hypervisor like Virtualbox try to add a dedicated nat-mode interface for internet access. and multiple interface for your bridges like br-mgmt br-vxlan and ..
