KVM Server端Bonding+Bridge配置
[root@localhost~]# more /etc/sysconfig/network-scripts/ifcfg-em2
DEVICE=em2
ONBOOT=yes
BOOTPROTO=static
USERCTL=no
MASTER=bond0

[root@localhost~]# more /etc/sysconfig/network-scripts/ifcfg-em3
DEVICE=em3
ONBOOT=yes

USERCTL=no
TYPE=Bridge
[root@localhost ~]# more /etc/modprobe.d/bonding.conf
alias bond0 bonding
options bond0 miimon=100 mode=4
启动两个vm,将其两个接口绑定到br10上．
[root@localhost ~]# brctl show
bridge namebridge idSTP enabledinterfaces
br10 8000.d4bed9b5bc21 no bond0
vnet0
vnet1
交换机配置，仅需开启port-channel(LACP协议)
测试:
1.Server1与server2向vm_server1和vm_server2施压
分别结果图:
Vm_server1
Vm_server2
Server1
Server2
2. vm_server1和vm_server2向Server1与server2施压
分别结果图:
Vm_server1
Vm_server2
Server1
Server2
3.server1各server2向vm_server1施压
分别结果图:
server1
Server2
Vm_Server1
从测试3可以看出，我们的vm_server1虚拟机可以接受近200Mb/s的流量.
