xen上创建多个虚拟网桥

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
               ;;
