If a CD or DVD device is to be made available to the guest operating system , the ''Mount CD/DVD Drive'' option must first be selected. Once selected, the remaining options on the screen are enabled. The CD/DVD device presented to the virtual machine may be in the form of a physical device connected to the host, or an ISO image file visible to the host operating system. In the case of an ISO image, the file must be added to the media library using the ''Virtual Media Manager'' before it can be attached to a virtual machine. To access the Virtual Media Manager, click on the button located to the right of the ISO image file menu.

The Network settings screen allows up to four network adapters to be configured on the virtual machine. Additional adapters (up to a total of eight) can be configured using the ''VBoxManage'' command-line tool. By default, a single network adapter is enabled for new virtual machines using NAT to access the network (whereby the virtual machine accesses the network using a network adapter installed in the host, but appears to other computers on the network using the same IP address as the host).

The settings screen also provides the option to enable USB 2.0 (ECHI) support. Once USB support is enabled, the physical USB devices which are to made available to the guest operating system are controlled by creating filters. These filters are added and removed using the button buttons in the vertical toolbar located on the right hand side of the list area.

The top button creates a filter which makes all USB devices available to the guest operating system. The second button displays a list of USB devices currently attached to the host computer and creates a filter for the device selected from the list. The third button alolows allows properties of the currently selected filter to be edited (such as the filter name, device vendor ID, product ID and manufacturer).
