VMDirectPath I/O allows a guest operating system on a virtual machine to directly access physical PCI and PCIe devices connected to a host. Each virtual machine can be connected to up to two PCI devices.

PCI devices connected to a host can be marked as available for passthrough from the Hardware Advanced Settings in the Configuration tab for the host.

To use VMDirectPath, the host must have Intel® Virtualization Technology for Directed I/O (VT-d) or AMD I/O Virtualization Technology (IOMMU) enabled in the BIOS. In order to add PCI devices to a virtual machine, the devices must be connected to the host and marked as available for passthrough. In addition, PCI devices can be added only to virtual machines with hardware version 7.
