`--nonrotational` (optional): This switch allows to enable the 
non-rotational flag for virtual hard disks. Some guests (i.e. Windows
7+) treat such disks like SSDs and don't perform disk fragmentation on
such media.
`--discard` (not implemented): This switch enables the auto-discard 
feature for the virtual hard disks. This specifies that a VDI image will
be shrunk in response to the trim command from the guest OS.
