Enabling virtualization in the bios will enable VT-d. There is not a specific breakout under virtualization for just VT-d.

Regards,

Thanks Geoff for your answer.

I'm trying to "passthrough" a PCIe GPU NVidia board with KVM.

This require VT-d support from both CPU and motherboard and to enable it from bios.

But even with Intel Virtualization Technology enabled when I try to attach device to VM I'm getting "No IOMMU found" from log. It seems that hardware doesn't have an IOMMU, or it is not configured correctly.

AFAYK there is something else to enable in order to succeed with PCI passthrough?

Thanks for your help.

Kindest regards,

Pietro
