|

12 | <p><b outputclass="bold">Input devices.</b> <ph conkeyref="vbox-conkeyref-phrases/product-name"/>
|

13 | can emulate a standard PS/2 keyboard and mouse. These devices
|
---|
14 | are supported by most guest OSes.
|

15 | </p>
|
---|
16 | <p>
|
---|
17 | In addition, <ph conkeyref="vbox-conkeyref-phrases/product-name"/> can provide virtual USB input
|
---|
18 | devices to avoid having to capture mouse and keyboard, as
|
---|
19 | described in <xref href="keyb_mouse_normal.dita#keyb_mouse_normal"/>.

23 | <p><b outputclass="bold">Graphics.</b> The default
|
---|
24 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/> graphics device for Windows guests is an SVGA
|
---|
25 | device. For Linux guests, the default graphics device emulates
|
---|
26 | a VMware SVGA graphics device. See
|
---|
27 | <xref href="settings-screen.dita#settings-screen"/>.
|
---|
28 | </p>
|
---|
29 | <p>
|
---|
30 | For legacy guest OSes, a VGA-compatible graphics device is
|
---|
31 | available.

|
---|
36 | emulates the most common types of hard disk controllers. See
|
---|
37 | <xref href="harddiskcontrollers.dita#harddiskcontrollers"/>. Whereas supporting
|
---|
38 | only one of these controllers would be enough for
|
---|
39 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/> by itself, this multitude of storage adapters
|
---|
40 | is required for compatibility with other hypervisors. Windows
|
---|
41 | is very selective about its boot devices, and migrating VMs
|
---|
42 | between hypervisors is very difficult or impossible if the
|
---|
43 | storage controllers are different.

53 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/> emulates the most common USB host
|

54 | controllers. See <xref href="usb-support.dita"/>.</p>
|
---|
55 | <p>The emulated USB controllers do not communicate directly with devices on the host.
|
---|
56 | Instead they communicate with a virtual USB layer that abstracts the USB protocol and
|
---|
57 | enables the use of remote USB devices. </p>
