A method of automatically virtualizing core native libraries of a virtual machine is disclosed. In an embodiment, the virtual machine is a java virtual machine (JVM). In this technique, the interface between the virtual machine and the core native libraries is controlled, since multiple instances of a core native library are loaded into the same process based on the number of co-located applications. Moreover, the interactions between the core native libraries and the underlying operating system (OS) are controlled so that a single point of contact is presented to the OS. Also, the dependencies the core native libraries may have on the virtual machine are handled.
