KVM对虚拟机映射scsi盘(2)

p> 

p>在根目录下面新建了个模板文件bruce.xml:

p> 

p> 

p> 

p><disk type="block" device="lun" sgio="unfiltered">

p><driver name="qemu" type="raw" cache="none" />

p><source dev="/dev/disk/by-path/kenny" />

p><target dev="sdyang" bus="scsi" />

p><shareable />

p><alias name="scsicontrollers-0-0-number" />

p><address type="drive" controller="controllers" bus="0" target="0" unit="number" />

p></disk>

p>然后通过以下脚本添加：

p> 

p>#!/bin/sh

p> 

p> 

p>controler=0

p>count=0

p>        ls /dev/disk/by-path/|grep -v part|grep fc|while read line

p>        do

p>                number=`echo $line|cut -d - -f 6`

p>                sed "s/kenny/$line/g" bruce.xml | sed "s/yang/$number$controler/g" |sed "s/controllers/$controler/g"|sed "s/number/$number/g" > /yang.xml

p>                echo "begin to attach device $number to xml file,controler is $controler ..."

p>                virsh attach-device bruce_yang /yang.xml --config 

p>                if test $? -eq 1

p>                then

p>                        echo "Failed to attach device to xml file ..."

p>                        exit 1

p>                fi

p>                count=`expr $count + 1`

p>                if test $count -eq 10

p>                then

p>                        count=0

p>                        controler=`expr $controler + 1`

p>                fi

p>        done
