腳本如下：

#!/usr/local/python3/bin/python3

import re,os,sys,time

mac_add = []

vir_name = sys.argv[1]

#打開給定的虛擬機名稱的xml文件來查找mac地址

with open('/etc/libvirt/qemu/%s.xml'%vir_name,'r') as f:

for line in f:

line = line.strip('\n')

if "mac address" in line:

mac_add.append(line)

#定用正則查出mac地址格式

result = re.findall(r'[0-9,a-z]+',mac_add[0],re.S)

mac_address = result[2] + result[3] + "." + result[4] + result[5] + "." + result[6] + result[7]

with open('/opt/script/ip_detail.txt','r') as f1:

for line in f1:

line = line.strip('\n')

if mac_address in line:

line = line.split('|')[0]

print(line)

註意：腳本中的ip_detail.txt文件內容是1.1.1.1|20|5254.007b.fc59|GigabitEthernet1/0/4格式為內容的文件，否則就要更改腳本中的line.split('\’)根據自己的情況修改即可。
