Unable to enable VT-x with Extended Page Tables (EPT)

Question

Hello,

I have a Dell PE R610 with Bios version 6.4.0 and Dual Processor X5650's, running server 2016 with Hyper-V.

The X5650 processor says it supports Intel® VT-x with Extended Page Tables (EPT). I have enabled Virtualization technology in the Bios but there no place to enable VT-x.
My question is if my processor supports EPT why am i unable to enable it? Coreinfo says it doesn't support EPT.

Coreinfo

HYPERVISOR * Hypervisor is present
VMX - Supports Intel hardware-assisted virtualization
EPT - Supports Intel extended page tables (SLAT)

Hello

There is not a BIOS option for VT-x. Enabling virtualization technology should be enough to enable VT-x. I just checked an R610 and EPT is listed as an available feature in the operating system. This could be an operating system compatibility issue.

Thanks

Hi, Did you have any luck getting EPT enabled? I've got a T610 running Win Server 2016 that I'm getting the exact same results on... Thanks.
