centos6.4重启网络报错Error: Connection activation failed: Device not managed by Networ

VMware中安装的centos6.4 64位，重启网络连接时，报以下错误：


Bringing up interface eth0: Error:Connection activation failed:Device not managed by NetworkManager

解决方法：（需要在ROOT下）

 1、Remove Network Manager from startup Services.

chkconfig NetworkManager off

2、Add Default Net Manager

chkconfig network on

3、Stop NetworkManager first

service NetworkManager stop

4、and then start Default Manager

 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
