Programatically detect if VT-x or AMD-v is enabled on Windows
提问by chromic
On OSX or linux, it is rather trivial to view CPU capabilities in the terminal. Is there a way to access the CPU information, specifically the hardware assisted virtualization capabilities, on Windows?
在 OSX 或 linux 上，在终端中查看 CPU 功能相当简单。有没有办法在 Windows 上访问 CPU 信息，特别是硬件辅助虚拟化功能？
I only found Microsoft's tool: http://www.microsoft.com/en-us/download/details.aspx?id=592
我只找到了微软的工具：http: //www.microsoft.com/en-us/download/details.aspx?id=592
but would like something that doesn't require additional binaries.
但想要一些不需要额外二进制文件的东西。

I believe the best bet to check if virtualisation is enabled is by using WMI and check the Win32_Processor class. The value of the "VirtualizationFirmwareEnabled" field should give you if it is enabled.
我相信检查是否启用虚拟化的最佳方法是使用 WMI 并检查 Win32_Processor 类。如果启用，“VirtualizationFirmwareEnabled”字段的值应该给你。
I have tested on my machine by enabling and disabling in the BIOS and this value appears correct.
我已经通过在 BIOS 中启用和禁用在我的机器上进行了测试，并且该值看起来是正确的。

For checking what is supported I believe you will need to use the __cpuid() intrinsic function with an Information type of 0x1 and 0x80000001 to query the CPU features. Examples can be found on the following links.
为了检查支持的内容，我相信您需要使用信息类型为 0x1 和 0x80000001 的 __cpuid() 内部函数来查询 CPU 功能。可以在以下链接中找到示例。
