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 six 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, verify that the host has Intel® Virtualization Technology for Directed I/O (VT-d) or AMD I/O Virtualization Technology (IOMMU) enabled in the BIOS.

Verify that the PCI devices are connected to the host and marked as available for passthrough.

Verify that the virtual machine is using hardware version 7.
