弹出界面 eth0: 错误:激活连接失败:Device not managed by NetworkManager or una

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

则检查自己的windows服务项

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