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.
