Why "Hyper-V Platform" feature is disabled?

Question

I tried to enable Hyper-v feature in Windows 8 Pro,

but "Hyper-V Platform feature is Disabled" ...

I get this message: hyper-v cannot be installed the processor does not have required virtualization capabilities

my processor : Core i7-3630QM

and this information by "systeminfo"

Hyper-V Requirements: VM Monitor Mode Extensions: No
                      Virtualization Enabled In Firmware: Yes
                      Second Level Address Translation: Yes
                      Data Execution Prevention Available: Yes

What problem is my computer does not support this feature?

Solution

I had a similar problem with my Lenovo x201i which was solved by enabling the "Intel(R) Virtulazation Technology" and "Intel(R) VT-d Feature" options in the BIOS

Just be aware that the wording of these options may be different for your version of the BIOS

Hyper-V Requirements: VM Monitor Mode Extensions: No Seems like it's this one. Are you running VMware as well?

[ScottJeffry]

No, VMware is not installed on my computer.

In Microsoft website: They say only Hardware requirements: has Second Level Address Translation

Perhaps social.technet.microsoft.com/wiki/contents/articles/… although I'm not sure the information is correct.

Your CPU should support VM Monitor Mode Extensions (called VT-x on Intel CPUs). Check your BIOS settings, it is probably disabled there. It might not explicitly be called VT-x though...

[ScottJeffry]

yes in My BIOS settings: "Intel Virtualization Technology" (VT-x) is enabled

[ScottJeffry]

in CPU-Z "Instructions" I have: "MMX, SSE, SSE2, SSE3, SSSE3, SSE4, SSE4.2, EM64T, VT-x, AES, AVX"
