环境：win10 VM虚拟机安装centos7
挂起重启后，重启网络服务报错
使用提示命令查看：systemctl status network 发现报错为Failed to start LSB: Bring up/down networking
百度说禁用NetworkManager，没有用。禁用启用后重启网卡恢复正常
解决方式：重启NetworkManager
1. systemctl stop NetworkManager
2. systemctl disable NetworkManager
3. systemctl enable NetworkManager
4. systemctl start NetworkManager
