Managing process migration from source virtual machine to target virtual machine which are on the same operating system

摘要

An apparatus and method for managing process migration are provided. When a process of a source virtual machine is to be migrated to a target virtual machine based on a process migration request, and the source virtual machine and the target virtual machine are on the same operating system (OS), logical migration is performed by updating information included in a virtual machine information database and a namespace router table.

1. An apparatus for managing process migration, comprising:
a hardware layer; and a migration manager configured to perform logical migration by updating information included in a virtual machine information database and information included in a namespace router table when a process of a source virtual machine is to be migrated to a target virtual machine on one operating system (OS) based on a process migration request, wherein the information included in the virtual machine information database comprises one or more virtual machines executed on the same OS, wherein the virtual machine information database includes attribute information of processes corresponding to process identifications (IDs) indicating whether the processes are migrated and lists of the process IDs of the processes operating in the virtual machines, wherein the information included in the namespace router table comprises information about one or more resources accessed by each migrated process according to migrated processes.
