windows-8.1 - Hyper V Windows 8.1 Pro 将无法运行。在 BIOS 中启用虚拟化

Question

I bought Windows 8.1 pro so I could use the Hyper-V Virtualisation. I have the correct Hardware - Intel(R) Core(TM) i5-4200M CPU @ 2.5GHZ - Toshiba C55-A-1N1.In TaskManager->Performance it saysVirtualisation:       DisabledHyper-V support:      YesIn Turn Windows features on or off Window for Hyper-V it saysHyper-V                                - ticked with a square tick(Partial tick)    Hyper-V Management Tools           - ticked         Hyper-V GUI Management Tools  - ticked          Hyper-V Module for Windows PowerShell                                       - ticked.    Hyper-V Platform                   - not able to tick (greyed out)Hyper-V manager opens but I cannot create a Virtual Machine.The laptop manufacture Toshiba have assured me that the laptop has the capability and it is a Microsoft problem. I spent 4+ hours getting bounced around Microsoft tele-operators/technicians repeating the same problem to each. I am now waiting on a call back I was promised two days ago. I am starting to think there is a known problem that no-body want to admit. So the question is.1. Does anyone know how to fix this? or 2. Is anyone aware of a bug in Windows 8.1 Pro resulting in Hyper-V not working? ********************************************************************Continuation after Answer from varun_mc********************************************************************This is the message I get from hovering over the greyed out checkbox Hyper-V Platform in Windows  Features."Hyper-V cannot be installed: Virtuallisation support is disabled in the firmware."This could mean Toshiba has turned it off for security or something. The output from coreinfo does not mention EPT, see below.**********************************************************************Intel(R) Core(TM) i5-4200M CPU @ 2.50GHzIntel64 Family 6 Model 60 Stepping 3, GenuineIntelMicrocode signature: 00000016HTT         *   Hyperthreading enabledHYPERVISOR  -   Hypervisor is presentVMX         *   Supports Intel hardware-assisted virtualizationSVM         -   Supports AMD hardware-assisted virtualizationX64         *   Supports 64-bit modeSMX         -   Supports Intel trusted executionSKINIT      -   Supports AMD SKINITNX          *   Supports no-execute page protectionSMEP        *   Supports Supervisor Mode Execution PreventionSMAP        -   Supports Supervisor Mode Access PreventionPAGE1GB     *   Supports 1 GB large pagesPAE         *   Supports > 32-bit physical addressesPAT         *   Supports Page Attribute TablePSE         *   Supports 4 MB pagesPSE36       *   Supports > 32-bit address 4 MB pagesPGE         *   Supports global bit in page tablesSS          *   Supports bus snooping for cache operationsVME         *   Supports Virtual-8086 modeRDWRFSGSBASE    *   Supports direct GS/FS base accessFPU         *   Implements i387 floating point instructionsMMX         *   Supports MMX instruction setMMXEXT      -   Implements AMD MMX extensions3DNOW       -   Supports 3DNow!

Pretty hard when you are buying over the internet.

将鼠标悬停在禁用的“Hyper-V 平台”选项上应该会提示您禁用它的原因:

以下是我要检查的几件事:

• 确保在 BIOS 中启用了硬件辅助虚拟化。
• 确保在 BIOS 中启用数据执行保护 (DEP)。
• 确保您的处理器是 64 位的并且具有二级地址转换 (SLAT) 功能。然后确认 SLAT 在 BIOS 中启用。

您可以使用 Sysinternal 的 CoreInfo.exe 来确定您的机器是否支持虚拟化和 SLAT。可以从 Microsoft Technet 站点下载该工具:http://download.sysinternals.com/files/Coreinfo.zip

从提升的命令提示符运行“CoreInfo.exe -v”。

如果您在这里看到“-”，则表示您的处理器不支持 SLAT；如果是“*”，则表示支持 SLAT。理想情况下，您应该在启用 Hyper-V 之前看到上面的输出。
