What does Intel VT-D do?

Intel VT-d makes direct access to a PCI device possible for guest systems with the help of the Input/Output Memory Management Unit (IOMMU) provided. This allows a LAN card to be dedicated to a guest system, which makes attainment of increased network performance beyond that of an emulated LAN card possible.

Should I disable Intel VT-D?

You must disable Virtualization Technology for Directed I/O (VT-d) in BIOS before you can use Oracle VM. This is necessary because input/output memory management unit (I/O MMU) is not supported in Oracle VM 3.2.
