Though from the research I did, unless you're running a Type 1 hypervisor vt-d is not necessary (or usable). Type 2 hypervisors will use vt-x only.

- venomsnake 13y agoIOMMU is needed for VGA and PCI passtrough in general.
- wtallis 13y agoWhat are your sources for that? VirtualBox seems to fall under "type 2", but supports PCI passthrough using VT-d on linux hosts.
- porker 13y agoAbout 10 hours of crawling through forums, VMWare documentation and a couple of conversations with people about ESXi. So all of it pretty unreliable ;) I'd love to see sources/evidence to the contrary.
- comex 13y agoVT-d is still useful without any hypervisor, to guard against DMA attacks by malicious connected devices.
