我已经使用 vagrant 安装了一个 Ubuntu VM。当我通过 SSH 进入 VM 并 ping google.com 时，它运行正常。大约一分钟后，我就停止接收数据包了。
重新获得互联网连接的唯一方法是vagrant halt然后vagrant up继续循环。
这是我的流浪文件：
Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/xenial64"
config.vm.provider :virtualbox do |vb|
vb.customize ['modifyvm', :id,'--memory', '2048']
vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
end
config.ssh.forward_agent = true
config.vm.network "forwarded_port", guest: 3333, host: 3333
config.vm.network "forwarded_port", guest: 3334, host: 3334
config.vm.network "public_network", ip: "172.20.0.0", bridge: "en1: Wi-Fi (AirPort)"
end

我希望我的虚拟机能够与外界通信，并且外界也可以与我的虚拟机通信。
而且我的主机有稳定的网络！
