问题背景:
       用1U服务器搭建预演环境,单台物理服务器上部署多个KVM虚拟机,宿主机操作系统部署完毕,支持虚拟化所用软件包安装完毕,宿主机和虚拟机连接的网卡br100配置完毕,需要启动,在启动br100和eth1时,突然报错如下:

[root@maker network-scripts]# ifup br100
错误:激活连接失败:Failed to determine connection's virtual interface name
[root@maker network-scripts]# ifup eth1
错误:激活连接失败:Master connection not found or invalid

解决办法:
[root@maker network-scripts]# chkconfig NetworkManager off
[root@maker network-scripts]# service NetworkManager stop
停止 NetworkManager 守护进程:                             [确定]
[root@maker network-scripts]# ifup eth1
[root@maker network-scripts]# ifup br100
[root@maker network-scripts]# ifconfig
