Abstract
Systems and methods are described for improving portability of virtual machine checkpoints without affecting system performance. In an example, a method includes determining, by a source computing system having a processor, via a virtual machine, and based on a runtime of an application on the virtual machine, one or more units of the application to compile as one or more non-portable units of the application; designating, as a non-entrant compiled code, the one or more non-portable units of the application, wherein the designation prevents execution of the one or more non-portable units; decompiling, by the source computing system, one or more stack frames associated with the one or more non-portable units of the application; sending, by the source computing system to a destination computing system, a checkpoint for the application; restoring, by the destination computing system via the virtual machine, from the checkpoint for the application, the runtime of the application.
