不但是要創建新的 VNIC，還要對應到實體上不同的網路卡上去。 參考文件 xen上創建多個虛擬網橋 Bridge 

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

        *)
                echo "Unknown command:${OP}"
                echo 'Valid commands are: start, stop, status'
                exit 1
               ;;
esac

設定為可執行檔：

# 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' ]

# chmod 重啟服務
