A hypervisor consolidates multiple numbers and multiple types of OSes into a single machine by multiplexing a real machine into a number of virtual machines (VMs). An example the typical application of a hypervisor is server consolidation which uses the same or similar types of VMs and OSes (symmetric). Another application is accommodating different types of OSes (asymmetric): open platform and closed platform, real-time and time sharing, general-purpose and dedicated purpose, emerging and legacy, etc. For instance, a mobile device consists of real-time OS, which controls radio transmissions, and general-purpose OS, which exposes highlevel API.
