Python 如何通过vmware SDK（pyvmomi）获取vm群集名称

我有获取虚拟机容量（名称等）的代码。但有一个问题：我需要获取这个VM的集群名称。如我所见，我们只能获取LUN名称，但不能获取群集名称

                """Getting data from vCenter and parsing It"""

                try:
                   serviceInstance = connect.SmartConnectNoSSL(host=datacenter,user=user,pwd=password)
                except:
                   print "Connection error or cannot retrieve data"

                content = serviceInstance.RetrieveContent()
                viewType = [vim.VirtualMachine]
                recursive = True
                container = content.rootFolder
                containerView = containerView = content.viewManager.CreateContainerView(container, viewType, recursive)
                children = containerView.view
                return children

        def data_processing(self):
                vcContent = self.getting_data()
                for child in vcContent:
                        print child.summary.config

这应该做到：

print(child.summary.runtime.host.parent.name)
