The Apple Software License Agreement for OS X Mountain Lion[1] is not your friend here. …you are granted a limited, non-transferable, non-exclusive license:… (iii) to install, use and run up to two (2) additional copies or instances of the Apple Software within virtual operating system environments on each Mac Computer you own or control that is already running the Apple Software, for purposes of: (a) software development; (b) testing during software development; (c) using OS X Server; or (d) personal, non-commercial use. So development, testing, running OS X Server, and non-commercial are the legal uses. The Mac OS Server license is more restrictive, a single copy on Apple branded hardware.
