Yes, when Intel virtualization technology is activated in BIOS, VT-d is typically enabled automatically.

Check the BIOS settings for your IBM or Lenovo system. Since you mentioned VT-d support, look for related configuration options there.
Are IOMMU groups necessary for hardware pass-through? Probably not—just ensure VT-x is enabled for basic virtualization needs. I’m unsure about your BIOS setup, but VT-d and VT-x are usually compatible in most configurations.
I'll require IOMMU support for a GPU pass-through since I'm running ProxMox.
You're interested in learning more about this system. It seems to be related to a ProXMOX user who has experience with hardware pass-through. I'm curious to know which IBM Server model and CPU you're using. Also, feel free to share your other question! Note that VT-d is disabled when VT-x is active, likely for security reasons.
What BIOS version do you have installed? These identifiers indicate a specific release—Version 1.23 with BuildID G0E122D. Are these newer or older than your current setup? You should ensure either VT-x is active or both VT-x and VT-d are enabled. VT-x provides general virtualization support, while VT-d offers hardware pass-through functionality. VT-d works alongside VT-x to enhance performance.
V1.23 marks the introduction of VT-d. It’s moments like these that remind me BIOS could be more uniform. I’m planning to search for videos to understand what you’re reviewing. Usually VT-x and VT-d are CPU-related features, so they’d appear in an advanced menu or under CPU settings. You might need to turn on IOMMU via North Bridge settings, though I’m unsure what was available back then with the LGA1567 socket.
Any luck? I couldn't find much information. From here I'd start sending BIOS screen shots so I know what you're looking at.
I'm currently occupied with school, so I'll probably experiment with it later. If things go wrong, I might call the seller tomorrow. Thanks for your help!
