I can't figure out what Coreinfo reports because I don't get the expected results on my systems and only one has an hypervisor running (Hyper-V) and Vt-d, but all have virtualization enabled.
(i) By enabing virtualization in the BIOS
(ii) EPT is on the processor and you can't enable or disable it in the BIOS
(iii) The B75 chipset does not support Vt-d (it's somewhat surprising it won't work with Vt-d or IOMMU)
(iv) Should be the Execute Disable Bit (XD) in the CPU Configuration section that should probably be enabled
Once again thanks mate and trust me it is the most confusing thing ever! The coreinfo says my machine is able to do all three of them. Intel says too and then I downloaded intel's processor identifying tool from their download center and ran it and it says yeah it can do virtualization but it can't do Vt-d! And funny enough it doesnt support trusted execution as well. So logically the both needed to be disabled but since i cant run either of them isn't it quite clear that i'd just pass the mark? And then WP SDK trolled me super hard and gave up another error message saying to disable both vt-d and trusted execution -_-
