Sun Microsystems VIRTUALBOX 3.0.0 - Manual (Page 117)

8 VBoxManage reference
Note: For compatibility with earlier versions of VirtualBox, the “registerim-
age” and “unregisterimage” commands are also supported and mapped inter-
nally to the “openmedium” and “closemedium” commands, respectively.
Note however that when you unregister a hard disk image using VBoxManage, it
will not be deleted from the host computer’s hard drive.
8.13 VBoxManage showhdinfo
This command shows information about a virtual hard disk image, notably its size, its
size on disk, its type and the VM it is in use by.
Note: For compatibility with earlier versions of VirtualBox, the “showvdiinfo”
command is also supported and mapped internally to the “showhdinfo” com-
mand.
8.14 VBoxManage createhd
This command creates a new virtual hard disk image. The syntax is as follows:
VBoxManage createhd --filename <filename>
--size <megabytes>
[--format VDI|VMDK|VHD] (default: VDI)
[--variant Standard,Fixed,Split2G,Stream,ESX]
