VMX hardware virtualization not supported

[vviskari]

Hi,

I'm trying to upgrade my Win7 guest to Win10 but it keeps saying "CPU not supported".
Something prevents the guest Win7 to detect the hardware correctly. For some reason the VMX feature is not available (checked with coreinfo.exe).

Running on 13" late '11 MBP, Yosemite, VirtualBox 5.0.0

Thanks in advance if anyone could help.

Here is part of my VM configuration:

VT-x/AMD-V are not visible in the guest because VirtualBox does not supported nested virtualization and does not pass these flags. That's an intended limitation.
VMX is a generic term, so maybe the exact CPU flag wanted would help here? But that would be a question for Microsoft.

OK, thanks.

I believe that is what is needed for the Windows 10 upgrade and I won't be upgrading it then.
