PyVmomi使用未连接的dv添加NIC('config.distributedVirtualSwitch'未设置)

Question

我使用下面的代码来添加配置DistributedVirtualSwitch到现有VM 的NIC (通过pyVmomi):

def __AddNIC(si, vmconf_dict, network_name):
    vm = __get_vm(si, vmconf_dict)
    print " Network label : " + network_name

    devices = []
    nicspec = vim.vm.device.VirtualDeviceSpec()
    nicspec.operation = vim.vm.device.VirtualDeviceSpec.Operation.add
    nicspec.device = vim.vm.device.VirtualVmxnet3()
    nicspec.device.wakeOnLanEnabled = True
    nicspec.device.deviceInfo = vim.Description()
    nicspec.device.connectable = vim.vm.device.VirtualDevice.ConnectInfo()
    nicspec.device.connectable.startConnected = True
    nicspec.device.connectable.allowGuestControl = True

    network_objref = _get_mor_by_property(si, vim.dvs.DistributedVirtualPortgroup, network_name)
    dswitch_port_connection = vim.dvs.PortConnection(
        portgroupKey=network_objref.key,
        switchUuid=network_objref.config.distributedVirtualSwitch.uuid
    )
    nicspec.device.backing = vim.vm.device.VirtualEthernetCard.DistributedVirtualPortBackingInfo()
    nicspec.device.backing.port = dswitch_port_connection

    devices.append(nicspec)
    vmconf = vim.vm.ConfigSpec(deviceChange=devices)
    task = vm.ReconfigVM_Task(vmconf)
    tasks.wait_for_tasks(si, [task])

我收到以下异常:

switchUuid = network_objref.config.distributedVirtualSwitch.uuid AttributeError:'NoneType'对象没有属性'uuid'

在检查Vcenter Managed Objects(通过mob)后,似乎 某些DistributedVirtualPortgroup对象引用确实具有that(VmwareDistributedVirtualSwitch)属性,而其他对象引用具有此属性Unset.

我尝试了多种方法来解决这个问题,例如:

• 设置: switchUuid=None产生:

  TypeError: Required field "switchUuid" not provided (not @optional)

• 设置: dswitch_port_connection = None产生:

  TypeError: Required field "port" not provided (not @optional)

注意:当我VMware WebClient用于配置上述功能时,它可以完美运行.

问题:如何添加像这样的网卡？

检查您的用户权限。您对端口组有 System.Read 权限吗？

定义端口组的分布式虚拟交换机。应始终设置此属性，除非用户的设置对此属性引用的对象不具有 System.Read 权限。
