Types of virtual machine

There are two types of virtual machines which are summarized below.    

1-System |Hardware based Virtual machine  

 "The system based virtual machine are those systems which have multiple logical/Isolated units for multiple users on a same physical system."    Advantage :    The most important advantage of pysical based VM is effective utilization of physical system.    

For Example:    

1-kernel based systems  

2-VMWare  

3-CloudBasedSystems    

2-Application based Virtual machine:

 Application based virtual machine is also known as processed(Software based) because of each applications have different runtimes to run corresponding applications.The best example i described that, to run java applications we need JVM engine,to run .NET applications we need CLR(Common Language Runtime) and to run Perl applications we need perl runtime.Each runtime have separate processs on a same environment.  

 For Example:    

1-Common Language Runtime (CLR) (for  .NET applications)  

2-JRE(JVM)  

3-Perl Runtime    

And finally, we can say that JVM falls under the category of application(Software) based virtual machine.
