8 VBoxManage 8.1 Introduction As briefly mentioned in chapter 1.13, Alternative front-ends, page 28, VBoxManage is the command-line interface to VirtualBox. With it, you can completely control VirtualBox from the command line of your host operating system. VBoxManage supports all the features that the graphical user interface gives you access to, but it supports a lot more than that. It exposes really all the features of the virtualization engine, even those that cannot (yet) be accessed from the GUI. You will need to use the command line if you want to • use a different user interface than the main GUI (for example, VBoxSDL or the VBoxHead- less server) • control some of the more advanced and experimental configuration settings for a VM. There are two main things to keep in mind when using VBoxManage: First, VBoxManage must always be used with a specific “subcommand”, such as “list” or “createvm” or “startvm”. All the subcommands that VBoxManage supports are described in detail in chapter 8, VBoxManage, page 99. Second, most of these subcommands require that you specify a particular virtual machine after the subcommand. There are two ways you can do this: • You can specify the VM name, as it is shown in the VirtualBox GUI. Note that if that name contains spaces, then you must enclose the entire name in double quotes (as it is always required with command line arguments that contain spaces). For example: VBoxManage startvm "Windows XP" • You can specify the UUID, which is the internal unique identifier that VirtualBox uses to refer to the virtual machine. Assuming that the aforementioned VM called “Windows XP” has the UUID shown below, the following command has the same effect as the previous: VBoxManage startvm 670e746d-abea-4ba6-ad02-2a3b043810a5 You can type VBoxManage list vms to have all currently registered VMs listed with all their settings, including their respective names and UUIDs. Some typical examples of how to control VirtualBox from the command line are listed below: • To create a new virtual machine from the command line and immediately register it with VirtualBox, use VBoxManage createvm with the --register option,1 like this: $ VBoxManage createvm --name "SUSE 10.2" --register VirtualBox Command Line Management Interface Version 4.0.4 (C) 2005-2011 Oracle Corporation All rights reserved. Virtual machine ’SUSE 10.2’ is created.
