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

［[e-mail] ~］# 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' ]
