实现能够创建多台虚拟机的脚本（虚拟机克隆）：
#!/bin/bash

IMG_DIR=/var/lib/libvirt/p_w_picpaths
BASE_VM=rhel6base
E_NOINPUT=65
E_NOTNUM=66
E_OUT_OF_RANGE=67

read -p "please input a vm number: " NEW_VMNU
if [ -z $NEW_VMNU ]; then
 echo "You must input a number."
 exit $E_NOINPUT
fi

if [ $NEW_VMNU != $(echo "$NEW_VMNU*1" | bc) ]; then
 echo "You must input a number."
 exit $E_NOTNUM
fi

if [ $NEW_VMNU -lt 1 -o $NEW_VMNU -gt 254 ]; then
 echo "You must input a number between 1 and 254"
 exit $E_OUT_OF_RANGE
fi

NEW_VM=${BASE_VM}node${NEW_VMNU}

if [ -e $IMG_DIR/$NEW_VM.img ]; then
 echo "$NEW_VM already exists"
 exit $E_VM_EXISTS
fi

echo -en "creating disk p_w_picpath......\t\t"
qemu-img create -b $IMG_DIR/$BASE_VM.img -f qcow2 $IMG_DIR/$NEW_VM.img &> /dev/null
echo -e "\e[32m[OK]\e[0m"
echo

virsh dumpxml $BASE_VM > /tmp/$BASE_VM.xml
