Python - VMWare vSphere (WEB SDK) - SUDS

问题:

How do i contact the vSphere (or VMWare) form Python either with some form of library or via SUDS to get the number of number of vCPU or a specific host/guest/virtual-machine?

Currently i'm trying:

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 

And that works, and it gives me some form of output:

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

I've tried following the following "guides":

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

I know that all the information probably is here, i just can't see the entire picture :/

After a while of trying this is where i get stuck:

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') 

And the output is:

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

You might want to try psphere, a Python library (based on suds) which will give you access the entire vSphere Web Services SDK.

Install it:

$ pip install psphere 

Find a virtual machine and print the number of CPUs it has:

>>> 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 

You can find more examples in the documentation.

Solved it with a new library: 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() 

It keeps the namespace intact of the vSphere variables and it's as transparent as i need it to be, meaning it doesn't change anything which makes it easy to find, it also support batching up information so i don't have to query through all 1500 servers one by one in a slow painful process, it takes a few seconds to gather information regarding any host.
