How to determine if hardware virtualization is available via code? (C#, C++)
提问by Raj Rao
How can I detect if a system supports hardware virtualization via code? (Preferably in C# or C++).
如何通过代码检测系统是否支持硬件虚拟化？（最好使用 C# 或 C++）。
I tried using WMI and ManagementObjectSearcher, and could not find a property that seemed to represent if virtualization support was present or not in the machine.
我尝试使用 WMI 和 ManagementObjectSearcher，但找不到似乎表示机器中是否存在虚拟化支持的属性。
Bonus question: Is it possible to tell if the CPU supports HW virtualization, but disabled in BIOS?
额外问题：是否可以判断 CPU 是否支持硬件虚拟化，但在 BIOS 中被禁用？

I think the original poster is asking how to detect that the computer hardware supports virtualisation, not that it is running inside a virtual machine. See this questionfor a possible answer.
我认为原始海报是在询问如何检测计算机硬件是否支持虚拟化，而不是它是否在虚拟机内运行。请参阅此问题以获得可能的答案。
Also, it might be worth seeing if you can check the CPU flags, as there will either be the Intel vmxflag or the AMD svmflag if the processor supports virtualisation extensions. I can't say I know how this should be done under Windows, but the information is available in /proc/cpuinfoon Linux.
此外，如果您可以检查 CPU 标志，可能值得一看，因为如果处理器支持虚拟化扩展，就会有 Intelvmx标志或 AMDsvm标志。我不能说我知道在 Windows 下应该如何做到这一点，但是/proc/cpuinfo在 Linux 上可以找到这些信息。

Check this link, as you can see there, maybe you should use WMI classes to get info. .NET framework has System.Management namespace to do that. Win32_processor class can give you all info you need about processor, because you can't access the cpu flags directly using win32_processor class, maybe you need to check the value of VirtualizationFirmwareEnabled
检查此链接，正如您在那里看到的那样，也许您应该使用 WMI 类来获取信息。.NET 框架有 System.Management 命名空间来做到这一点。Win32_processor 类可以为您提供有关处理器的所有信息，因为您无法使用 win32_processor 类直接访问 cpu 标志，也许您需要检查 VirtualizationFirmwareEnabled 的值

I do not have a C-ish answer, but here's a PowerShell approach -- it's just a simple WMI query -- that can help.
我没有 C 语言的答案，但这里有一个 PowerShell 方法——它只是一个简单的 WMI 查询——可以提供帮助。
Query Win32_Processor; there are flags "SecondLevelAddressTranslationExtensions" and "VirtualizationFirmwareEnabled." They seem to answer the questions for me.
查询 Win32_Processor; 有标志“SecondLevelAddressTranslationExtensions”和“VirtualizationFirmwareEnabled”。他们似乎在为我回答问题。
In PoSH, it's
在 PoSH 中，它是
(GWMI Win32_Processor).VirtualizationFirmwareEnabled
(GWMI Win32_Processor).VirtualizationFirmwareEnabled
and
和
(GWMI Win32_Processor).SecondLevelAddressTranslationExtensions
(GWMI Win32_Processor).SecondLevelAddressTranslationExtensions
I hope this helps.
我希望这有帮助。
