| 91 | <para>
|
|---|
| 92 | The <command>VBoxManage guestproperty</command> command enables
|
|---|
| 93 | you to set or retrieve the properties of a running virtual machine
|
|---|
| 94 | (VM). See <xref linkend="guestadd-guestprops" />. Guest properties
|
|---|
| 95 | are arbitrary name-value string pairs that can be written to and
|
|---|
| 96 | read from by either the guest or the host. As a result, these
|
|---|
| 97 | properties can be used as a low-volume communication channel for
|
|---|
| 98 | strings provided that a guest is running and has the Guest
|
|---|
| 99 | Additions installed. In addition, the Guest Additions
|
|---|
| 100 | automatically set and maintain values whose keywords begin with
|
|---|
| 101 | <literal>/VirtualBox/</literal>.
