= Closed-source features =

The following list shows the features that are unique to the closed source [wiki:"Editions" edition] of !VirtualBox. Note that this list may change over time as previously closed source features are made available for the open source version as well.

 * '''Remote Display Protocol (RDP) Server'''

 This component implements a complete RDP server on top of the virtual hardware and allows users to connect to a virtual machine remotely using any RDP compatible client.

 * '''USB support'''

 !VirtualBox implements a virtual USB controller and supports passing through USB 1.1 and USB 2.0 devices to virtual machines.

 * '''USB over RDP'''

 This is a combination of the RDP server and USB support allowing users to make USB devices available to virtual machines running remotely.

 * '''Shared Folders'''

 With the use of Shared Folders, users can share directories on their host system with guest systems.

 * '''iSCSI initiator'''

 !VirtualBox contains a builtin iSCSI initiator making it possible to use iSCSI targets as virtual disks without the guest requiring support for iSCSI.
