python xmlrpc的学习一例（获取kvm信息）

python xmlrpc的学习一例（获取kvm信息）

服务端代码：

#!/usr/bin/env python

#-*- coding: utf-8 -*-

from SimpleXMLRPCServer import SimpleXMLRPCServer

from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler

import json

import libvirt

import socket

#获取本机电脑名

myname = socket.getfqdn(socket.gethostname(  ))

#获取本机ip

myaddr = socket.gethostbyname(myname)

print myaddr

conn = libvirt.open("qemu:///system")

class RequestHandler(SimpleXMLRPCRequestHandler):

   rpc_paths = ('/RPC2',)

try:

   server = SimpleXMLRPCServer((myaddr,8000),

                                 requestHandler=RequestHandler)

except Exception,e:

   print e

#server.register_instance()

server.register_introspection_functions()

def get_kvm_list():

   dom = conn.listDomainsID()

   return dom

def get_kvm_info(domain):

   dom = conn.lookupByID(domain)

   infos = dom.info()

   print infos

   print dom.name()

   infodir = {}

   infodir['id'] = domain

   infodir['Name'] = dom.name()

   infodir['state'] = infos[0]

   infodir['MaxMemory'] = infos[1]

   infodir['CPUS'] = infos[3]

   infodir['CPUTIME'] = infos[2]

   return infodir

server.register_function(get_kvm_list,'kvmlist')

server.register_function(get_kvm_info,'kvminfo')

server.serve_forever()

客户端代码：

#!/usr/bin/env python

#-*- coding: utf-8 -*-

import xmlrpclib

KVMhost = '192.168.0.109'

x = xmlrpclib.ServerProxy("http://%s:8000"%KVMhost)

print x.system.listMethods()

a =x.kvmlist()

print a

for i in a:

   dir = x.kvminfo(i)

   print "=================================================="

   print "Id is :",dir['id']

   print 'domain Name is :',dir['Name']

   print 'State is :',dir['state']

   print 'Max Memory is :', dir['MaxMemory']

   print 'Num of cpu is :',dir['CPUS']

   print 'Cpu time is :',dir['CPUTIME']

运行结果：

[root@c03 xmlserver]# python kvmmonitorCiletn.py

['kvminfo', 'kvmlist', 'system.listMethods', 'system.methodHelp', 'system.methodSignature']

[4, 15]

==================================================

Id is : 4

domain Name is : winxp

State is : 1

Max Memory is : 1048576

Num of cpu is : 1

Cpu time is : 1048576

==================================================

Id is : 15

domain Name is : salttest

State is : 1

Max Memory is : 1048576

Num of cpu is : 1

Cpu time is : 1048576

简单的练习下xmlrpc的使用。用来获取宿主主机上面的虚拟机的信息。打算用来集中管理kvm。：）
