Multiple Virtual Machines (MVM) personality

A historical note

The term “MVM” goes from OS/2 (PowerPC). It replaces the term “MVDM” (Multiple Virtual DOS Machines). The PowerPC platform could not so easily emulate the Intel processor real mode, so it required more emulation. Though, we must say that it worked just fine, fast, and theoretically may be used not for DOS only. (IBM had plans to provide a binary compatibility with OS/2 (Intel), on the base of the same component which was used to run DOS Apps).
