106 <para>
107 The <command>VBoxManage guestproperty</command> command enables
108 you to set or retrieve the properties of a running virtual machine
109 (VM). See <xref linkend="guestadd-guestprops" />. Guest properties
110 are arbitrary name-value string pairs that can be written to and
111 read from by either the guest or the host. As a result, these
112 properties can be used as a low-volume communication channel for
113 strings provided that a guest is running and has the Guest
114 Additions installed. In addition, the Guest Additions
115 automatically set and maintain values whose keywords begin with
116 <literal>/VirtualBox/</literal>.

135 The <command>VBoxManage guestproperty enumerate</command> command
136 lists each guest property and value for the specified
137 VM. Note that the output is limited if the guest's service is
138 not updating the properties, for example because the VM is not
139 running or because the Guest Additions are not installed.
