Posted 2023-05-06

参考技术A Bringing up interface eth0: Error:Connection activation failed:Device not managed by NetworkManager

解决方法：

1、Remove Network Manager from startup Services.

[root@localhost ~]# chkconfig NetworkManager off

2、Add Default Net Manager

[root@localhost ~]# chkconfig network on

3、Stop NetworkManager first

[root@localhost ~]# service NetworkManager stop

4、and then start Default Manager

[root@localhost ~]# service network start

5、然后重新启动网络，可能还会出现以下信息，可以不用管，也可以重启一下电脑主机,我是重启了下机器

6. 重启机器后

service network restart

如果出现

则检查自己的windows服务项

开启其中的VMware NAT Service和VMnetDHCP服务即可。
