VIRTUAL MACHINE DISK MIGRATION
First Claim
1. A method of migrating a source virtual machine disk of a virtual machine from a first storage device to a second storage device while the virtual machine is running, the method comprising:
- creating a target virtual machine disk in the second storage device;
replicating the source virtual machine disk of the first storage device to the target virtual machine disk in the second storage device;
detecting variation of the source virtual machine disk;
reflecting the detected variation on the replication stored in the target virtual machine disk in the second storage device; and
assigning the target virtual machine disk of the second storage device as a designated virtual machine disk for the virtual machine.

Abstract
A method and an apparatus may be provided for migrating a source virtual machine disk of a virtual machine from a first storage device to a second storage device while the virtual machine is running. The method may include creating a target virtual machine disk in the second storage device, replicating the source virtual machine disk of the first storage device to the target virtual machine disk in the second storage device, detecting variation of the source virtual machine disk, reflecting the detected variation on the replication stored in the target virtual machine disk in the second storage device, and assigning the target virtual machine disk of the second storage device as a designated virtual machine disk for the virtual machine.

17. A virtual machine for migrating a virtual machine disk from a first storage device to a second storage device while the virtual machine is running, the virtual machine comprising:
-
a migration unit configured to create a target virtual machine disk in the second storage device and to replicate the source virtual machine disk of the first storage device to the target virtual machine disk in the second storage device; a snapshot controller figured to detect variation of the source virtual machine disk and to create a snapshot of the detected variation; and a virtual machine disk controller configured to assign the target virtual machine disk of the second storage device as a designated virtual machine disk for the virtual machine, wherein the migration unit is configured to reflect the detected variation on the replication stored in the target virtual machine disk in the second storage device based on the snapshot. - View Dependent Claims (18, 19, 20)
