Python - VMWare vSphere (WEB SDK) - SUDS

Question

如何使用某种形式的库或通过SUDS联系vSphere (或VMWare) form Python，以获得vCPU或特定主机/客户/虚拟机的数量？

目前我正在尝试：

from suds.client import Client
from suds.sudsobject import Property

client = Client("https://<server>/sdk/vimService?wsdl")
queryCon = client.wsdl.services[0].ports[0].methods['QueryConnectionInfo']
print queryCon

这是可行的，它给了我某种形式的输出：

(Method){
   name = "QueryConnectionInfo"
   location = "https://localhost/sdk/vimService"
   binding =
      (binding){
         input = <suds.bindings.document.Document instance at 0x0775C080>
         output = <suds.bindings.document.Document instance at 0x0775C080>
      }
   soap =
      (soap){
         action = ""urn:vim25/4.1""
         style = "document"
         input =
            (Input){
               body =
                  (Body){
                     parts[] =
                        (Part){
                           root = <part name="parameters" element="vim25:QueryConnectionInfo"/>
                           name = "parameters"
                           qname[] =
                              "parameters",
                              "urn:vim25",
                           element = "(u'QueryConnectionInfo', u'urn:vim25')"
                           type = "None"
                        },
                     use = "literal"
                     namespace[] =
                        "vim25",
                        "urn:vim25",
                     wrapped = True
                  }
               headers[] = <empty>
            }
         output =
            (Output){
               body =
                  (Body){
                     parts[] =
                        (Part){
                           root = <part name="parameters" element="vim25:QueryConnectionInfoResponse"/>
                           name = "parameters"
                           qname[] =
                              "parameters",
                              "urn:vim25",
                           element = "(u'QueryConnectionInfoResponse', u'urn:vim25')"
                           type = "None"
                        },
                     use = "literal"
                     namespace[] =
                        "vim25",
                        "urn:vim25",
                     wrapped = True
                  }
               headers[] = <empty>
            }
         faults[] =
            (Fault){
               name = "InvalidLoginFault"
               use = "literal"
               parts[] =
                  (Part){
                     root = <part name="fault" element="vim25:InvalidLoginFault"/>
                     name = "fault"
                     qname[] =
                        "fault",
                        "urn:vim25",
                     element = "(u'InvalidLoginFault', u'urn:vim25')"
                     type = "None"
                  },
            },
            (Fault){
               name = "HostConnectFaultFault"
               use = "literal"
               parts[] =
                  (Part){
                     root = <part name="fault" element="vim25:HostConnectFaultFault"/>
                     name = "fault"
                     qname[] =
                        "fault",
                        "urn:vim25",
                     element = "(u'HostConnectFaultFault', u'urn:vim25')"
                     type = "None"
                  },
            },
            (Fault){
               name = "RuntimeFault"
               use = "literal"
               parts[] =
                  (Part){
                     root = <part name="fault" element="vim25:RuntimeFaultFault"/>
                     name = "fault"
                     qname[] =
                        "fault",

                     element = "(u'RuntimeFaultFault', u'urn:vim25')"
                     type = "None"
                  },
            },
      }
 }

我试着遵循以下“指南”：

SUDS - programmatic access to methods and types

http://www.vmware.com/support/developer/vc-sdk/visdk41pubs/ApiReference/vim.VirtualMachine.html#field_detail

http://communities.vmware.com/thread/273616

我知道所有的信息可能都在这里，我只是看不到整个画面:/

在尝试了一段时间之后，这就是我被卡住的地方：

client = Client("https://<server>/sdk/vimService?wsdl")
#queryCon = client.wsdl.services[0].ports[0].methods['QueryConnectionInfo']
print client.service.QueryConnectionInfo("https://<server>/sdk", None, r'domain\user', 'Password')

输出结果为：

urllib2.URLError: <urlopen error [Errno 1] _ssl.c:490: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol>

Answer 1

您可能想尝试使用psphere，这是一个Python库(基于suds)，它将使您能够访问整个vSphere Web Services SDK。

安装它：

$ pip install psphere

查找虚拟机并打印其拥有的CPU数量：

>>> from psphere.client import Client
>>> from psphere.managedobjects import VirtualMachine
>>> client = Client(server="vcenter.mydomain.com", username="Administrator", password="strong")
>>> vm = VirtualMachine.get(client, name="genesis")
>>> vm
<psphere.managedobjects.VirtualMachine object at 0xd3fbccc>
>>> print("%s has %s CPUs" % (vm.name, vm.config.hardware.numCPU))
genesis has 2 CPUs

您可以在documentation中找到更多示例。

免责声明：我是psphere的作者。

用一个新的库解决了这个问题: pysphere (easy_install pysphere)

from pysphere import VIServer
server = VIServer()
server.connect("server", 'user', "pass")
vm = server.get_vm_by_name("virtual_host_name")
info = vm.get_properties()

它保持了vSphere变量的名称空间的完整性，并且它是我想要的那样透明，这意味着它不会改变任何容易找到的东西，它还支持批量信息，所以我不必在缓慢而痛苦的过程中逐个查询所有1500台服务器，它需要几秒钟来收集任何主机的信息。
