7 <p>It is currently not possible to manipulate EFI variables from within a running guest. For example, setting the
8 <codeph>boot-args</codeph> variable by running the <userinput>nvram</userinput> tool in a Mac OS X guest will
9 not work. As an alternative method, <codeph>VBoxInternal2/EfiBootArgs</codeph> extradata can be passed to a VM in
10 order to set the <codeph>boot-args</codeph> variable. To change the <codeph>boot-args</codeph> EFI variable, use
11 the following command: </p>
12 <pre xml:space="preserve">VBoxManage setextradata "VM name" VBoxInternal2/EfiBootArgs &lt;value&gt;</pre>
