asked on

VT-x is not supported on win2008?

Hello,
Our company just bought two identical motherboards (ASUS P8H77-V LE) and two identical CPU (Core i7 3770), the only difference is that I have installed Windows 2008R2 x64 and my coworker has installed Windows 7 x64.
When I tried to install the Intel® HAXM (Hardware Accelerated Execution Manager) which I need to run the Android emulator, I got a message that VT-x is not supported. Intel Processor Identification utility confirms: "Intel(R) VT-x with Extended Page Tables: No". But on his machine everything works fine, VT-x is detected.
I've checked the BIOS setup setting, the Intel Virtualization option is enabled.

Is it an OS limitation or I just got a bad motherboard or what?

Can a BIOS update help?

Is Intel-VT enabled in the BIOS?

check and run the following:-

Secureable

Is Intel-VT enabled in the BIOS?
Yes, I checked and double checked that.
Secureable says just NO,
I've attached the Coreinfo result.
coreinfo.txt
have you enabled Hyper-V ? eg added the role

if so you will need to disable

Hyper-V conflicts and masks Intel-V, coreinfo states hypervisor is present.

Yes, I thought about the Hyper-V which is enabled too. But I tried to remove the Hyper-v role and got the following message:
Attempting to un-install Hyper-V failed with error code 0x80070026. Reached the end of the file
okay, it is because of Hyper-V , it cannot be removed, but can be disabled.

 “bcdedit /set hypervisorlaunchtype off” and reboot the server.

then re-check with coreinfo, secureable

see if you have Intel VT

How do I disable the Hyper-V ? I've stopped it and made "Disabled" all three services I found which name starts with "Hyper-V", then cold rebooted. Did not change a thing.

I'm attaching the screen shot from my BIOS setup and the list of all services, just in case.
