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
