8 VBoxManage
8.22 VBoxManage getextradata/setextradata
These commands let you attach and retrieve string data to a virtual machine or to a
VirtualBox configuration (by specifying global instead of a virtual machine name).
You must specify a key (as a text string) to associate the data with, which you can
later use to retrieve it. For example:
VBoxManage setextradata Fedora5 installdate 2006.01.01
VBoxManage setextradata SUSE10 installdate 2006.02.02
would associate the string “2006.01.01” with the key installdate for the virtual machine Fedora5, and “2006.02.02” on the machine SUSE10. You could retrieve the
information as follows:
VBoxManage getextradata Fedora5 installdate
which would return

8.23 VBoxManage setproperty
This command is used to change global settings which affect the entire VirtualBox
installation. Some of these correspond to the settings in the “Global settings” dialog in
the graphical user interface. The following properties are available:
hdfolder This specifies the default folder that is used to keep disk image files (.vdi,
.vmdk, .vhd).
machinefolder This specifies the default folder in which virtual machine definitions
are kept; see chapter 9.1, VirtualBox configuration data, page 151 for details.
vrdpauthlibrary This specifies which library to use when “external” VRDP authentication has been selected for a particular virtual machine; see chapter 7.1.5, RDP
authentication, page 109 for details.
websrvauthlibrary This specifies which library the web service uses to authenticate
users. For details about the VirtualBox web service, please refer to the separate
VirtualBox SDK reference (see chapter 11, VirtualBox programming interfaces,
page 184).
hwvirtexenabled This selects whether or not hardware virtualization support is enabled by default.
