   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。

  1

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

  2

  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

  1

  service NetworkManager stop

  然后重新执行

  1

  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
