Abstract
This application discloses a virtual machine (VM) hot migration method, an apparatus, and a storage medium. A method for virtual machine (VM) hot migration is described. Processing circuitry of a first host machine identifies that a memory block in a storage device of the first host machine is allocated to a virtual machine to migrate. Further, the processing circuitry determines whether the memory block is data-containing. When the memory block is data-containing, interface circuitry of the first host machine sends data in the memory block to a second host machine. When the memory block is not data-containing, the memory block is skipped for migration.
