问题原因：

win系统上 VMware NAT service 服务未开启

Centos7系统依赖于Windos上的VMWare虚拟出的硬件环境，本身硬件环境是虚拟出来的但是实际上是Windows的硬件环境分配，在Windows系统的服务中关闭了VMware NAT service服务进程，导致虚拟机无法启动NAT的网络模式。

解决方案：

1、启动任务管理器

win10系统按 win + x 选择 任务管理器

2、选择服务项开启 VMware NAT service

3、重启一下网络并查看网络状态

systemctl restart network
systemctl status network

4、问题验证

4.1 Centos7桌面右上角有网络连接标识

4.2 终端进行百度网址ping测试
