VT-d and VT-x not working, but set in BIOS

[PauliT]

I’m trying to get VT-x (and VT-d) to work on my HP ZBook 15 G4 (Intel Core i7-7820HQ). I saw discussion about similar case here: https://h30434.www3.hp.com/t5/Business-Notebooks/Intel-Virtualization-Technologies-VT-d-and-VT-x-not...

I’ve already done following tricks without luck:

• BIOS updated to latest version 01.18, 20.3.2018
• Deep sleep turned off (BIOS)
• Hyperthreading turned off (BIOS)
• Of course, VTx and VTd turned on (BIOS)
• Installed SP80322 (Conexant)
• Installed newer version than sp81835 (Synaptics Touchpad)

But still regarding Intel Processor Identification Utility “Intel VT-X with Extended Page Tables” is “No” (and I cannot get Virtualbox working correctly).

• Win10 cumulative update 1709 was installed before I started working with Virtualbox and these VTx/VTd-related things.
• I’ve also tried tried to disable Hyper-V from cmd/PowerShell and also install/uninstall it to be sure that it has been uninstalled.
  • bcdedit /set hypervisorlaunchtype off
  • Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
  • dism.exe /Online /Disable-Feature:Microsoft-Hyper-V-All

What I could try next?

PauliT,

It probably doesn't make you feel any better but I'm suffering the same problem and did exactly as you did below.

I tried with the latest BIOS ... 01.22 Rev.A, Jun 12, 2018

I got this very nice workstation-class machine that I can't install VMs on - I tried with Virtualbox and VMWARE.

This makes it pretty useless for my purposes.

Any help, suggestions gratefully accepted.

Thanks!

Dan.

I've the same issue. This is bothering me for a long time.

No way to install android emulator.

VT-x is certainly enabled in BIOS, however, intel processor information app shows it's not.

I also disabled Hyper-V in many different ways and restarted many times, didn't help.

So frustrating that such a high-end zbook has this kind of issue.
