OS X can be placed on a flash drive that can be booted independently. This capability has been available for many years. I once installed OS X onto my Gen 1 iPod just for the sake of it. If you're using a virtual machine, it doesn't matter much since VM "drives" function like self-contained files. They'll show up as files on the drive and can be moved around like regular files.
