是否有可能使用C＃来检查是否启用硬件虚拟化？ [英] Is it possible using C# to check if hardware virtualization enabled?

问题描述

找不到答案，所以我想我要求自己。

使用C＃，我怎么能检测CPU是否启用了硬件虚拟化？的Hyper-V，例如。这不是在 Win32_Processor 类，我尝试连接到 MSVM_ComputerSystem 与彻底的失败满足。不断告诉我有一个无效的命名空间。

代码的下方。

  ManagementObjectSearcher VM =新ManagementObjectSearcher（@\\.\root\virtualization，SELECT * FROM MSVM_Computersystem）; 
 ManagementObjectCollection vmCollection = vm.Get（）; 
的foreach（在vmCollection的ManagementObject MO）
 {
 cpuVirtual = MO [EnabledState]的ToString（）。 
} 
  

解决方案

如果您枚举所有属性Win32_Processor类，你会看到一个名为财产 VirtualizationFirmwareEnabled ，我认为你是在谈论这个属性。

正如你可以看到的此链接，检查是否一些机处理器能够在Hyper-V上运行，它们使用 VirtualizationFirmwareEnabled 结合其他性能：

我写了这个简单的文档片断遍历所有win32_processor类值：

  ManagementClass managClass =新ManagementClass（win32_processor）; 
 ManagementObjectCollection managCollec = managClass.GetInstances（）; 
 
的foreach（的ManagementObject managObj在managCollec） 
 {
的foreach（在managObj.Properties VAR道具）
 {
 Console.WriteLine（物业名称：{0}值：{1}，prop.Name，道具.value的）; 
} 
} 
 
 Console.ReadKey（）; 
  

Couldn't find an answer, so I thought I ask for myself.

Using C#, how can I check if the CPU has hardware virtualization enabled? Hyper-V, for example. It's not in the Win32_Processor class, and my attempt to connect to the MSVM_ComputerSystem was met with utter failure. Keeps telling me there's an invalid namespace.

Code below.

ManagementObjectSearcher vm = new ManagementObjectSearcher(@"\\.\root\virtualization", "select * from MSVM_Computersystem");
ManagementObjectCollection vmCollection = vm.Get();
foreach (ManagementObject mo in vmCollection)
{
     cpuVirtual = mo["EnabledState"].ToString();
}

解决方案

if you enumerate all properties in Win32_Processor class, you see a property named "VirtualizationFirmwareEnabled", I think you are talking about this property.

As you can see in this link, to check if some machine processor can run on Hyper-V, they use VirtualizationFirmwareEnabled" in conjunction to other properties:

I wrote this simple snipped to iterate over all win32_processor class values:

ManagementClass managClass = new ManagementClass("win32_processor");
ManagementObjectCollection managCollec = managClass.GetInstances();

foreach (ManagementObject managObj in managCollec)
{
   foreach (var prop in managObj.Properties)
   {
       Console.WriteLine("Property Name: {0} Value: {1}",prop.Name,prop.Value);
   }               
}

Console.ReadKey();
