KVM之Bonding＋Bridge实验

测试环境：

名字	ip	OS	Bonding+Bridge	Speed
KVM	192.168.x.57	Centos6.3	Y	200Mb/s
Vm_server1	192.168.x.61	Centos6.3	N	可变
Vm_server2	192.168.x.62	Centos6.3	N	可变
Server1	192.168.x.130	Centos6.0	N	100Mb/s
Server2	192.168.x.254	Centos5.5	N	100Mb/s

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

SLAVE=yes

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

DEVICE=em3

ONBOOT=yes

BOOTPROTO=static

USERCTL=no

MASTER=bond0

SLAVE=yes

[root@localhost~]# more /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0

ONBOOT=yes

BRIDGE=br10

[root@localhost~]# more /etc/sysconfig/network-scripts/ifcfg-br10

DEVICE=br10

ONBOOT=yes

BOOTPROTO=static

NM_CONTROLLED="no"

IPADDR=192.168.x.57

NETMASK=255.255.255.0

BROADCAST=192.168.x.255

NETWORK=192.168.x.0

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.
