Abstract
A system and method are disclosed for live migration of a virtual disk of a virtual machine between storage devices. In accordance with one example, a computer system prepares a first area of a first storage device and a second area of a second storage device for a live snapshot of a virtual disk of a virtual machine. A transaction is then executed that comprises: storing the live snapshot in the first area of the first storage device, copying the live snapshot to the second area of the second storage device, and mirroring a change to the virtual disk that occurs after the creation of the live snapshot, where the mirroring is via one or more write operations to the live snapshot in the first area and to the copy of the live snapshot in the second area.
