使用PowerCLI .net C＃重新启动VM

Question

我已经和这个墙碰壁了。目标是使用PowerCLI的API和C＃重新启动VM。这将是一个MVC框架。用户在登录页面和登录页面上会获得要重新启动的服务器列表。选择服务器，然后重新启动其中一个或多个（复选框）。

我的问题是了解PowerCLI和我所需要的。当前，我引用了VMware.Vim，它可以允许我连接并获取服务器列表。但是，我不确定如何通过API重新启动服务器。以下是我安装的库。我不确定除VMware.Vim之外还需要其他什么来实现此目的。

我目前正在将此youtube视频用作starting point。但是，将不胜感激任何文档，代码示例或任何指导。这有点超出我的水平，并且完全不熟悉PowerCLI。

More documentation.

非常感谢您的宝贵时间，

这是我在.net中用来重新启动VM的代码。您唯一需要的库是VMware.Vim。

1. 首先，获取与您的vcenter连接的客户端

public static VimClient ConnectToVCenter(string vCenterUrl, string username, string password)
{
    ServicePointManager.ServerCertificateValidationCallback = ((sender, certificate, chain, sslPolicyErrors) => true);

    VimClient client = new VimClientImpl();
    try
    {
        client.Connect($"https://{vCenterUrl}/sdk");
    }
    catch (Exception ex)
    {
        throw new ApplicationException($"Unable to connect to [{vCenterUrl}]. Exception: [{ex.Message}]");
    }
    client.Login(username, password);
    return client;
}

2. 获取虚拟机

public static VirtualMachine GetVM(VimClient client, string guestVM, ManagedObjectReference parentMoRef = null)
{
    // Lookup VM in vCenter.
    NameValueCollection Filter = new NameValueCollection
    {
        { "name", guestVM }
    };

    List<VirtualMachine> virtualMachines = GetEntities<VirtualMachine>(client, parentMoRef, Filter, null);

    // Do some error checking to make sure your VM was found.
    return virtualMachines.FirstOrDefault();
}

// Helper function that can be used to look up various objects like VirtualMachine, Datastore, etc.
public static List<T> GetEntities<T>(VimClient vimClient, ManagedObjectReference beginEntity, NameValueCollection filter, string[] properties)
{
    return vimClient.FindEntityViews(typeof(T), beginEntity, filter, properties)?.Cast<T>().ToList();
}

3. 启动或关闭或重新启动VM

// Use enum for power operations
public enum PowerOp
{
    suspend,
    reset,
    powerOff,
    gracefulOff,
    powerOn,
    powerOnWaitForTools,
    gracefulReboot,
    standby
}

public static void PowerOperation(VimClient client, VirtualMachine vm, PowerOp operation)
{
    switch (operation)
    {
        case PowerOp.suspend:
            if (vm.Runtime.PowerState != VirtualMachinePowerState.suspended)
                client.WaitForTask(vm.SuspendVM_Task());
            break;

        case PowerOp.reset:
            client.WaitForTask(vm.ResetVM_Task());
            break;

        case PowerOp.powerOff:
            if (vm.Runtime.PowerState != VirtualMachinePowerState.poweredOff)
            {
                client.WaitForTask(vm.PowerOffVM_Task());
            }
            break;

        case PowerOp.powerOn:
            if (vm.Runtime.PowerState != VirtualMachinePowerState.poweredOn)
            {
                client.WaitForTask(vm.PowerOnVM_Task(vm.Runtime.Host));
            }
            break;

        case PowerOp.powerOnWaitForTools:
            if (vm.Runtime.PowerState != VirtualMachinePowerState.poweredOn)
            {
                client.WaitForTask(vm.PowerOnVM_Task(vm.Runtime.Host));
            }
            vm.WaitForTools(client);
            break;

        case PowerOp.gracefulReboot:
            vm.RebootGuest();
            Thread.Sleep(10000); // Wait at least 10 seconds to let the server start with reboot.
            vm.WaitForTools(client);
            Thread.Sleep(5000); // Just a precaution.
            break;

        case PowerOp.gracefulOff:
            if (vm.Runtime.PowerState != VirtualMachinePowerState.poweredOff)
                vm.ShutdownGuest();
            vm.WaitForPowerState(client, VirtualMachinePowerState.poweredOff);
            break;

        case PowerOp.standby:
            vm.StandbyGuest();
            break;

        default:
            throw new ApplicationException($"Error: Unknown power operation requested");
    }
}
