vmware api开发之快照管理

公司要自己开发私有云管理平台，我这边负责vmware部分的后台接口编写。主要基于vmware官方的 python 接口 pyvmomi进行二次封装，主要实现有虚拟机开关机注销；
虚拟机增删磁盘；虚拟机快照增删还原；虚拟机 html5的console界面虚拟机网络管理zabbix 监控 esxi的磁盘使用率 zabbix 接受转发esxi的报警信息本文展示快照功能，快照其实是一个很小的功能，主要是让大家了解下vmware快照的接口，网上没有干过我这个事情，中间有个遍历的算法
先上图
1实际效果



2、实际的数据




代码如下
from pyVmomi import vim
from pyVim.connect import SmartConnect, Disconnect
import atexit
import argparse
import getpass
import ssl
import random
import cgi, cgitb
import sys
import json

def wait_for_task(task):
""" wait for a vCenter task to finish """
task_done = False
while not task_done:
if task.info.state == 'success':
return task.info.result

if task.info.state == 'error':
print ("there was an error")
task_done = True
form = cgi.FieldStorage()
vmnames= form.getvalue('IP')

si = None
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_NONE
si = SmartConnect(host="10.20.11.3",
user="root",
pwd="vmware",
port=443,
sslContext=context)
atexit.register(Disconnect, si)
content = si.RetrieveContent()

container = content.viewManager.CreateContainerView(content.rootFolder, [vim.VirtualMachine], True)
for c in container.view:
if c.name == vmnames:
obj = c
break

try:
obj.name
except Exception as e:
res={'status':'failed','result':'IP is not found'}
body = json.dumps(res)
print ("Status: 200 OK")
print ("Content-Type: application/json")
print ("Content-Length: %d" % (len(body)))
print ("")
print (res)
sys.exit()

output=[]
#遍历快照的树状结构 注意要设置为全局变量
def showlist(snapshot):

global output

output.append({snapshot.snapshot:[snapshot.name,snapshot.createTime.timestamp()]})

for i in snapshot.childSnapshotList:
showlist(i)
