A computer system includes a software virtual machine (such as Java) for running one or more applications. An object is provided that is responsive to a call from an application for placing the virtual machine and application into a state of suspension. This involves interrupting all current threads, and recording the state of the components of the virtual machine, including heap, threads, and stack, into a serialization data structure. Subsequently the serialization data structure can be invoked to resume the virtual machine and application from the state of suspension. Note that many virtual machines can be cloned from the single stored data structure. One benefit of this approach is that a new virtual machine can effectively be created in an already initialized state.
