Xen下为虚拟机增加多网桥操作

由于xen提供的脚本/etc/xen/script/network-bridge只能一个个建立，所以我们如要开机就启动2个虚拟网桥，必须作如下操作

vi /etc/xen/script/network-custom

#!/bin/sh

# network-xen-custom

# Exit if anything goes wrong

set -e

# First arg is operation.

OP=$1

#shift

script=/etc/xen/scripts/network-bridge

case ${OP} in

start)

$script start vifnum=0 bridge=xenbr0 netdev=eth0

$script start vifnum=1 bridge=xenbr1 netdev=eth1

;;

stop)

$script stop vifnum=0 bridge=xenbr0 netdev=eth0

$script stop vifnum=1 bridge=xenbr1 netdev=eth1

br1 netdev=eth1

;;

status)

$script status vifnum=0 bridge=xenbr0 netdev=eth0

$script status vifnum=1 bridge=xenbr1 netdev=eth1

;;

*)

echo "Unknown command:${OP}"

echo 'Valid commands are: start, stop, status'

exit 1

;;

esac

［root@lordling.com ~］# chmod a+x network-custom

修改/etc/xen/xend-config.sxp

(network-script network-bridge ) －－》 (network-script network-custom )

DOMU configuration file:

vif = [ 'type=ioemu,bridge=xenbr0','type=ioemu,bridge=xenbr1' ]

[root@lordling.com ~］# chmod

重启服务

brctl show查看

cat /proc/net/dev | grep peth*|face
