vSphere DirectPath 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.

Snapshots are not supported with PCI vSphere DirectPath I/O devices.

To use DirectPath, 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 or later.


Select a virtual machine.

In the virtual machines and templates inventory tree, select a group of virtual machines and select a virtual machine from the list on the right.

Search for a virtual machine and select it from the search results list.


In the VM Hardware panel, click Edit Settings.


Click Virtual Hardware.


From the Add a device drop-down menu, select PCI Device and click Add device.


Select the passthrough device to connect to the virtual machine from the drop-down list and click Next.
