【问题描述】：
我正在关注basic Vagrant tutorial，Vagrant 在我的 Ubuntu 上提供了一个盒子，没有抱怨。此外，我可以vagrant ssh 进入虚拟机。但是，无法从主机访问 VM：无法 ping 它的 IP 地址。
我所取得的成就：
- 已安装 VirtualBox (5.1.24 r117012 (Qt5.5.1)) 和 Vagrant (1.9.7) 到我的 Ubuntu (16.04.2 LTS) 机器上。
- 为 VM 提供了
vagrant up，Vagrant 完成了工作并且没有抱怨。 -
vagrant ssh有效。 - 我已经在来宾VM上手动安装了
lighttpd，我可以在来宾VM中成功ping/curl地址：localhost。
这是我尝试从主机访问来宾虚拟机时得到的结果：
~/tmp/myfirstvagrantproject$ ping 172.22.22.22
PING 172.22.22.22 (172.22.22.22) 56(84) bytes of data.

以下是工件：
1.Vagrantfile:

end
config.vm.provision :hostmanager
end
2.ifconfig 在来宾虚拟机上：

4.VirtualBox -> 设置 -> 网络显示：
- 适配器 1. 附加到：NAT
- 适配器 2。连接到：仅主机适配器
vboxnet0，已连接电缆 - 是的。
问题：如何配置 Vagrant/VirtualBox 以向主机操作系统公开 IP/端口？
【问题讨论】：
-
您是否提供了一些可能是
pingable的服务？你可以在vm上安装例如lighttpd并在浏览器中打开http://172.22.22.22吗？ -
感谢@RandallFlagg。我之前在VM上安装过Jenkins，这次我只是安装了lighttpd，我可以从guest VM成功
curl localhost，但是来自主机的curl 172.22.22.22失败curl: (7) Failed to connect to 172.22.22.22 port 80: Network is unreachable。
