METHOD, APPARATUS, AND SYSTEM FOR MANAGING MIGRATION OF VIRTUAL MACHINE

摘要

Disclosed is a method for managing migration of a virtual machine. The method comprises: compute, according to a migration parameter of a virtual machine to be migrated, a migration time of migrating the virtual machine to be migrated from a source computing node to a destination computing node, where the migration parameter comprises an allocated memory size, a memory change rate, and a migration network bandwidth of the virtual machine to be migrated; acquiring a current available migration time of the source computing node and a current available migration time of the destination computing node separately; and if neither the current available migration time of the source computing node nor the current available migration time of the destination computing node is not shorter than the migration time, determining to migrate the virtual machine to be migrated from the source computing node to the destination computing node. Further disclosed are an apparatus and a system for managing migration of a virtual machine. By means of the present invention, the accuracy of decision making for migration of a virtual machine can be improved to a certain degree.
