It is my understanding that Virtualization is NOT another name for VT-D.
Question: to enable virtualization on a motherboard is it true that the BIOS must have a feature named "virtualization" or something similar, and that just having a feature named "VT-d" and enabling it is not enough to enable virtualization.
Thanks,
Bill

Your processor should support:
- Intel® Virtualization Technology (VT-x)
- Intel® Virtualization Technology for Directed I/O (VT-d)
- Intel® VT-x with Extended Page Tables (EPT)
And, you must have a motherboard whose BIOS supports and allows you to enable virtualization.

I have seen postings elsewhere where people ask how to enable virtualization and the response has been look in the BIOS and enable VT-d.
Question: am I correct in thinking that enabling VT-d is not the same as enabling Virtualization.
Thanks,

I have not seen them broken apart in the bios. Enabling virtualization is the only setting I have seen. But, who knows - depends on the motherboard manufacturer's bios.

Hi Doc,
Thanks for the quick responses.
I'm looking at https://www.youtube.com/watch?v=5PYroA_whjU
Bios, Chipset menu
@6:57 into the video
shows VT-d and no Virtualization
One of the comments about the video said:
"I'm sorry but you did not mention virtualization technology on the mother board. I have the same mother board and i'm struggling with these option because I can't find it."
I am worried that if I were to buy the Gigabyte AORUS Z370 Ultra Gaming motherboard, I would not be able to enable Virtualization.
Question: is it possible that Gigabyte is using the characters "VT-d" to imply/cover Virtualization AND Intel's VT-d?
Thanks,
Bill

That is a good question for gigabyte to answer.

Since VT-d is an extension of VT-x and it is so rare to not enable VT-d along with VT-x, it is not unreasonable to say that they are synonymous. That is, since enabling VT-d requires that VT-x be enabled, let enabling VT-d (also) imply that VT-x should be enabled.
(Is that a gobbledygook statement or what? Say it quickly five times)
Bottom line, I do not believe that you have anything to be worried about. You can't have VT-d without VT-x.
Hope this helps,
...S

Thanks for all of your responses.
I have been communicating with the VirtualBox forum. The consensus there seems to be that
- virtualization is NOW always enabled in the BIOS and cannot be disabled.
- VT-d is still a BIOS option that one can enable/disable.
I will communicate with Asus and Gigabyte and see if I the person responding sounds like they know what they are talking about.
This topic could have been avoided if Intel had added more words to this page:
https://www.intel.com/content/www/us/en/virtualization/virtualization-technology/intel-virtualization-technology.html
And the motherboard manufacturers had and done the same for their motherboards.
I have no more questions for you folks.
Thanks,
Bill

Enabling or disabling Intel VT-d
- From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > System Options > Virtualization Options > Intel (R) VT-d and press Enter.
- Select a setting and press Enter.
- Enabled—Enables a hypervisor or operating system supporting this option to use hardware capabilities provided by Intel’s Virtualization Technology for directed I/O.
- Disabled—Does not enable a hypervisor or operating system supporting this option to use hardware capabilities provided by Intel’s Virtualization Technology for directed I/O.
- Press F10.
Regards,
Adrian
