　　Oracle Linux 6桥接网卡

　　最近把公司一台老掉牙的旧HP格式化了进行Linux虚拟化，安装一些测试服务器。操作系统使用的是Oracle Linux 6.4，虚拟机使用了KVM。

　　前面安装都非常顺利，但是到了设置网卡桥接的时候却出现了问题，像以前5.x一样设置的br0配置文件根本就没用，只要一桥接就会出错，网卡和桥接的虚拟网卡都报错。

　　eth0: Connection activation failed: Master connection not found or invalid

　　br0:Conncetion activation failed: Failed to determine connection’s virtual interface name

　　但是配置桥接文件却应该没错才是，最后经过网上查看，才知道是NetworkManager的问题。

　　按照说明停止NetworkManager服务

　　service NetworkManager stop

　　然后重新执行

　　service network restart

　　网卡桥接配置成功。我估计网上很多教程都是按照纯命令行方式写的，，如果另外安装了桌面有很多配置可能不一样。

　　附网卡和桥接配置文件

　　ifcfg-br0

　　TYPE=Bridge

　　BOOTPROTO=static

　　IPADDR=172.16.10.177

　　NETMASK=255.255.255.0

　　PREFIX=24

　　GATEWAY=172.16.10.1

　　NAME="System br0"

　　ONBOOT=yes

　　ifcfg-eth0

　　TYPE=Ethernet

　　#UUID=b67f5325-d513-40da-bc49-f16b473a8f6e

　　ONBOOT=yes

　　NM_CONTROLLED=yes

　　#BOOTPROTO=none

　　IPADDR=172.16.10.177

　　NETMASK=255.255.255.0

　　PREFIX=24

　　GATEWAY=172.16.10.1

　　DNS1=8.8.8.8

　　DEFROUTE=yes

　　IPV4_FAILURE_FATAL=yes

　　IPV6INIT=no
