Android : Is dalvik virtual machine a class?

I read on http://www.techotopia.com/index.php/Understanding_Android_Application_and_Activity_Lifecycles#Android_Process_States that each instance of a Dalvik virtual machine can run applications. I know a virtual machine is something that can run applications? Does that mean a Dalvik virtual machine has an actual class file(I implied that it does bc you can create instances of it)? I tried searching it for the actual class file of the Dalvik virtual machine but couldn't find anything
