Note: VirtualBox uses a consistent binary representation of UUIDs on all platforms. For this reason
the integer fields comprising the UUID are stored as little endian values. If you want to pass such
UUIDs to code which assumes that the integer fields are big endian (often also called network byte
order), you need to adjust the contents of the UUID to e.g. achieve the same string representation.
The required changes are:
 * reverse the order of byte 0, 1, 2 and 3
 * reverse the order of byte 4 and 5
 * reverse the order of byte 6 and 7.
Using this conversion you will get identical results when converting the binary UUID to the string
representation.
