问题描述

提示：使用Xftp 7传递文件时发现连接不上虚拟机，回到虚拟机一看网络没了，network和NetworkManager都没工作，启动服务出现如下报错

Job for network.service failed because the control process exited with error code. 
See "systemctl status network.service" and "journalctl -xe" for details.

---

解决方案：

先是将虚拟机网络模式由Net模式改为桥接模式，进去后发现NetworkManager启动了，但是network还是没启动，于是退出继续改为Net模式，进去后关闭NetworkManager

systemctl stop NetworkManager 关闭

systemctl disable NetworkManager 禁用

注意要disable后再开启network

systemctl start network

然后ping一下主机和www.baidu
