For instance, a dedicated physical graphics card attached to a physical system can be directly attached to a virtual machine, which then becomes responsible for managing it, a technique called *passthrough*. The PCI-SIG standards provide IOMMU-related specifications to allow a host operating system to not have a driver for a particular device and passthrough the device to the guest. The guest will have a device with nearly native performance, and use the standard vendor's drivers for the device. * The PCI-SIG standards also provide a way to partition compatible devices using so-called Virtual Functions (VFs). In this case, the host manages the way a physical device is used by the guest. Both host and guest must have specific device drivers.
