vSphere，通过API将现有的HDD添加到VM中(Govmomi)

Question

我试图将现有的HDD从一个虚拟机添加到另一个虚拟机。我使用golang和这个api：https://github.com/vmware/govmomi

首先，我从源vm获得如下磁盘：

for _, device := range devices {
        currentDeviceLabel := device.GetVirtualDevice().DeviceInfo.GetDescription().Label
        if strings.Contains(strings.ToLower(currentDeviceLabel), "hard disk"){
        disks = append(disks, device)
    }    
return disks

然后我尝试将接收到的磁盘添加到其他VM中：

func addDisk(vm *object.VirtualMachine, disk types.BaseVirtualDevice) {

    ctx, cancel := context.WithCancel(context.Background())
    defer cancel()

    spec := types.VirtualMachineConfigSpec{

        DeviceChange : []types.BaseVirtualDeviceConfigSpec {

            &types.VirtualDeviceConfigSpec{

                Operation: types.VirtualDeviceConfigSpecOperationAdd,
                FileOperation: types.VirtualDeviceConfigSpecFileOperationCreate,
                Device: disk,
            },

        },
    }

    result, err := vm.Reconfigure(ctx, spec)
    if err != nil {
        log.Fatal(fmt.Sprintf("err: %s", err.Error()))

    }

我从vSphere那里得到了错误：

Cannot complete the operation because the file or folder [xxxxx] xxxxx/xxxxx.vmdk already exists

我做错什么了？谢谢!

我在这里得到了答案：https://github.com/vmware/govmomi/issues/790

工作代码：

spec := types.VirtualMachineConfigSpec{}
config := &types.VirtualDeviceConfigSpec{
    Device:    disk,
    Operation: types.VirtualDeviceConfigSpecOperationAdd,
}
spec.DeviceChange = append(spec.DeviceChange, config)

result, err := vm.Reconfigure(ctx, spec)
if err != nil {
    log.Fatal(fmt.Sprintf("err: %s", err.Error()))

}
