内核版本:

Linux server-68 3.12.21-1.el6.x86_64 #1 SMP Thu Jun 5 22:15:05 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux

 

交换机与服务器Linux正常做配置

RH2288H V3 服务器在做完bond网卡绑定后,底层CentOs与底层的上层的KVM虚拟机无法通信。

解决方案

Linux中输入一下命令:关闭 gso gro lro

ethtool -K bond0 gso off

ethtool -K eth0 gso off

ethtool -K eth1 gso off

ethtool -K bond0 gro off

ethtool -K eth0 gro off

ethtool -K eth1 gro off

ethtool -K bond0 lro off

ethtool -K eth0 lro off
