Abstract
The present disclosure is a new and innovative system, methods and apparatus live storage migration. In an example, a system includes a memory and processor in communication with the memory. The processor is configured to receive a request to perform live storage migration of a guest managed by a source hypervisor on a source machine to a destination machine. The guest is configured to store data in blocks of block storage. The source hypervisor, executing on the processor, receives a hint for each block of data in block storage of the guest via an agent of the guest, wherein the hint relates to properties of a specific block of data. The source hypervisor then determines an efficient prioritization that identifies which blocks to copy and in what order as a part of the live storage migration based on the hints received from the agent. The source hypervisor then copies the blocks of data identified for copying in the migration based on the prioritization, saving time and computational resources.
