VMware 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. This direct path or passthrough can improve performance for VMware vSphere systems that utilize high‐speed I/O devices such as 10 Gigabit Ethernet
