线上服务器，安装CentOS 7.2 x64最小化安装，需要做链路聚合，双网卡绑定。在CentOS 6.x 和 CentOS 7上测试都OK，于是直接开搞。
说明下，以下环境是在虚拟机中实现的：
系统： CentOS 7.2 x64 最小化安装。
为了方便演示，这里共有三张网卡：
eno16777736 ： 桥接网卡：10.0.0.11/24
剩下的两张网卡准备做绑定：
eno33554984
eno50332208

到这里都没毛病。
[root@linuxidc ~]# nmcli con up team0 Error: Connection activation failed: NetworkManager plugin for 'team' unavailable
什么鬼？NetworkManager "team"插件不可用。于是开始排查。
是否存在team模块
[root@linuxidc ~]# lsmod | egrep *team*
木有。那直接restart network好了。
[root@linuxidc ~]# systemctl restart network Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details. [root@linuxidc ~]# systemctl status network ...

一样的报错，难道什么包没有安装到？
[root@linuxidc ~]# yum list all | grep NetworkManager* NetworkManager.x86_64 1:1.0.6-27.el7 @anaconda NetworkManager-libnm.x86_64 1:1.0.6-27.el7 @anaconda NetworkManager-tui.x86_64 1:1.0.6-27.el7 @anaconda NetworkManager-wifi.x86_64 1:1.0.6-27.el7 @anaconda NetworkManager-adsl.x86_64 1:1.0.6-27.el7 yum NetworkManager-bluetooth.x86_64 1:1.0.6-27.el7 yum NetworkManager-glib.x86_64 1:1.0.6-27.el7 yum NetworkManager-libreswan.x86_64 1.0.6-3.el7 yum NetworkManager-libreswan-gnome.x86_64 1.0.6-3.el7 yum NetworkManager-team.x86_64 1:1.0.6-27.el7 yum NetworkManager-wwan.x86_64 1:1.0.6-27.el7 yum
哎哟，还真有个NetworkManager-team没有安装叻。
[root@linuxidc ~]# yum install NetworkManager-team -y
然后再次尝试：
