VIRTUAL MACHINE DISK MIGRATION APPARATUS AND METHOD THEREOF

摘要

Disclosed are a virtual machine disk migration apparatus and a method thereof. The virtual machine disk migration apparatus completes migration by copying a virtual machine disk of a first physical disk for a virtual machine which is currently running onto a second physical disk, determining a fluctuation of the virtual machine disk within the first physical on the basis of the second physical disk and reflecting the determined fluctuation in the second physical disk, changing the second physical disk into a new virtual machine disk for the virtual machine and determining the unreflected fluctuation of the virtual machine disk of the first physical disk on the basis of the second physical disk, and finally reflecting the determined fluctuation in the second physical disk.
