vSphere VMware.Vim Clone_VM 'The operation is not allowed in the current state.'

Question

我的团队正在开发一个需要在我们的 vSphere 环境中克隆现有模板的应用程序。我们在 C# 应用程序中使用 VMware.Vim 来执行此操作。我们正在替换使用 PowerShell 的现有实施。

下面是抛出错误的代码。我们最终会根据内存使用情况进行负载平衡，但目前我们是随机选择主机。这就是为什么有一些额外的代码来收集所有主机然后选择一个。

当它到达 CloneVM_Task 时，抛出消息 'The operation is not allowed in the current state.' 的异常。这个异常并没有给我太多帮助，我在 vSphere 中找不到任何有用的日志。 vSphere 只是在事件日志中显示 "An error prevented the virtual machine from being cloned"。我们正在使用 6.7 版。我是 VMWare 的新手，所以感谢您的帮助。至少可以说，他们的文件是缺乏的。

在大多数情况下，您的代码看起来不错。我建议更改规范文件并使用尽可能少的信息从现有模板创建克隆。成功后，您可以添加更多详细信息并查看是否出错。

从这个开始，看看它是否能让你继续下去。

private VirtualMachineCloneSpec CreateCloneSpec(Datastore selectedStore, ManagedObjectReference randomHost, ClusterComputeResource cluster, VirtualMachine sourceVm)
{
    var mySpec =  new VirtualMachineCloneSpec
    {
        Location = new VirtualMachineRelocateSpec
        {
            Datastore = selectedStore.MoRef,
            Host = randomHost,
            Pool = cluster.ResourcePool
        },
        PowerOn = false,
        Template = false
    };

    return mySpec;
}

如果以上都通过，则添加 VirtualMachineRelocateTransformation 以根据需要将胖 VM 转换为瘦 VM 和网络连接。
