Vagrant为第二个VM创建额外的网桥

我正在尝试通过一个文件创建两个虚拟机：

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.vm.box_version = "1707.01"

  config.vm.define "inf-vm-01" do |node|
    config.vm.hostname = "inf-vm-01"
    config.vm.network "public_network", bridge: "en0: Wi-Fi (AirPort)", ip: "192.168.1.121"
  end

  config.vm.define "inf-vm-02" do |node|
    config.vm.hostname = "inf-vm-02"
    config.vm.network "public_network", bridge: "en0: Wi-Fi (AirPort)", ip: "192.168.1.122"
  end
end

如您所见，我想在每台来宾计算机和我的主机之间建立一座桥梁。问题是第二个虚拟机有一个额外的网桥。这是ip地址的输出：

我的vagrant文件有什么问题？

您有一个错误的vagrant文件，您正在块内使用

config.vm.network

，因此它对该文件有效。您应该这样写（注意我是如何在块内使用node1和node2变量的）

您还可以阅读，特别是章节
