VirtualBox Ubuntu / xenial64 VM不断丢失互联网连接

1

我使用vagrant安装了一个Ubuntu VM。当我通过SSH连接到VM并ping google.com时，它运行正常。大约一分钟，然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 并且循环继续。

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

VirtualBox适配器1 ： NAT

VirtualBox适配器2 ： Bridged Adapter (en0: Wi-Fi airport)

我希望我的虚拟机能够与外界进行通信，外界可以与我的虚拟机进行通信。

我的主机也有稳定的互联网！

做 /var/log/syslog 和 /var/log/kern.log 在您的Ubuntu VM中有什么关于网络接口的说法吗？

没有。他们都是空的
