+To make this change persistent you can use the `sysfsutils` Debian package.
+After installation configure it via */etc/sysfs.conf* or a `FILE.conf' in
+*/etc/sysfs.d/*.
+
+VM Configuration
+^^^^^^^^^^^^^^^^
+
+After creating VFs, you should see them as separate PCI(e) devices when
+outputting them with `lspci`. Get their ID and pass them through like a
+xref:qm_pci_passthrough_vm_config[normal PCI(e) device].
+
+Other considerations
+^^^^^^^^^^^^^^^^^^^^
+
+For this feature, platform support is especially important. It may be necessary
+to enable this feature in the BIOS/EFI first, or to use a specific PCI(e) port
+for it to work. In doubt, consult the manual of the platform or contact its
+vendor.
+
+Mediated Devices (vGPU, GVT-g)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Mediated devices are another method to reuse features and performance from
+physical hardware for virtualized hardware. These are found most common in
+virtualized GPU setups such as Intels GVT-g and Nvidias vGPUs used in their
+GRID technology.
+
+With this, a physical Card is able to create virtual cards, similar to SR-IOV.
+The difference is that mediated devices do not appear as PCI(e) devices in the
+host, and are such only suited for using in virtual machines.
+
+
+Host Configuration
+^^^^^^^^^^^^^^^^^^
+
+In general your card's driver must support that feature, otherwise it will
+not work. So please refer to your vendor for compatible drivers and how to
+configure them.
