Virtual machines are divided into two major classifications, based on their use and degree of correspondence to any real machine. They are either a system virtual machine or a process virtual machine.

Modern machines do not consist of multiple levels of virtual machines; that is a function of the host operating system's virtual machine manager and its guest operating systems, all of which are implemented through software. The operating system's virtual machine manager exposes one or more virtual machines upon which you can host one or more guest operating systems and their applications. In order to execute compiled Java applications upon one of these guest operating systems you will also need to install the Java virtual machine for that specific operating system. Thus you end up with a Java program executing within a Java virtual machine executing within a virtual machine executing within a virtual machine manager executing upon the physical hardware. The physical hardware itself may be optimised to handle virtual machine managers more efficiently, but the virtual machine manager is a software program; it is not part of the physical machine architecture
Mean Machines was created in 1990.
Virtual server hardware is used to facilitate in the creation of virtual machines. Virtual machines execute programs like physical machines.
Appeal Virtual Machines was created in 1998.
HP Integrity Virtual Machines was created in 2005.
The main advantage is that,the virtual machines reduces the hardware usage. In virtual machines we can load different OS.
VM servers are virtual servers. They are used to allow remote access to virtual machines. They can run virtual machines created by other VM products.

VMware and Windows Virtual PC
In general, encapsulation is the inclusion of one thing within another thing so that the included thing is not apparent.
It can use either: real hard drives and virtual ones.

This is a reference to a science fiction movie called The Matrix. In it, people were trapped in a virtual reality world and were really slaves to machines. If you're caught in the matrix, you're trapped in a virtual reality.
