    摘要: A method, apparatus, and system of virtual machine migration using local storage are disclosed. In one embodiment, a method includes creating a current snapshot of an operating virtual machine on a source physical server, storing a write data on a low-capacity storage device accessible to the source physical server and a destination physical server during a write operation on the destination physical server, and launching the operating virtual machine on the destination physical server when a memory data is copied from the source physical server to the destination physical server. The current snapshot may be a read-only state of the operating virtual machine frozen at a point in time. A time and I/O that may be needed to create the current snapshot that may not increase with a size of the operating virtual machine.
