KVM 多网卡绑定（流量聚合）

随着虚拟化技术不断发展与普及，越来越多的企业搭建和使用自己的虚拟化平台，这里我发一个KVM 虚拟化自动安装脚本，里面包含多网卡自动聚合配置，网卡绑定模式为4（流量叠加），脚本如下：（当然才mode=4模式，还需要在交换机配置网卡绑定）

附: ifcfg-eth0内容：

DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
TYPE=Ethernet
NM_CONTROLLED=no

附: modprobe.conf内容：
alias bond0 bonding
options bond0 miimon=100 mode=4

H3C交换机端需要做的配置如下： 

system-view
interface Bridge-Aggregation 100
link-aggregation mode dynamic
quit
interface GigabitEthernet1/0/28
port link-aggregation group 100
quit
interface GigabitEthernet1/0/29
port link-aggregation group 100
quit
interface GigabitEthernet1/0/33
port link-aggregation group 100
quit
interface GigabitEthernet1/0/30
port link-aggregation group 100
quit
