Closed-source features

The following list shows the features that are unique to the closed source 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.
