A virtual machine may be a software implementation of a
machine (i.e. a computer) that executes programs sort of a physical machine.
Virtual machines are separated into 2 major categories, supported their use and
degree of correspondence to any real machine. A system virtual machine provides
a whole system platform that supports the execution of a whole operating system
(OS).
Virtual machines are used to
produce an environment separate from the host operative environment. As every
machine works independently with its own storage and process power, one server
will have multiple such environments. Users will use them to make and test
applications without worrying concerning affecting the host operating system.
There’s no threat of work obtaining halted if the machine crashes
down. Because it is separate from the principal, it may be rebooted and work
may be carried out usually. This permits lots of flexibility and engineering
power to the users.
In distinction, a process virtual machine is intended to run
one program, which implies that it supports one process. a vital characteristic
of a virtual machines is that the
software running inside is limited to the resources and abstractions provided
by the virtual machine—it cannot break out of its virtual setting.
