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.
