Virtual Machine technology intercepts the call of
the upper software interface on the bottom through the
new Virtual layer and explains and re-processing the
call, in order to share resources, management and
coordination in heterogeneous environment, and
Support the application to make large-scale deploy,
relocation and operation and maintenance. Through the
virtual machine, a virtual computer simulation can be
setup in the original hardware and operating system
resources that make it possible that the software can
run without modification directly in the virtual
machine.
