Abstract: The present application discloses a virtual machine migration method and apparatus. A specific implementation of the method includes: receiving a migration request for migrating a virtual machine, wherein to-be-migrated data of the virtual machine comprises local data locally stored and shared data accessible by the virtual machine at a plurality of locations; determining migration operations respectively corresponding to the local data and the shared data in response to the migration request; and executing the migration operations corresponding to the local data and the shared data, to complete migration of the virtual machine. This implementation achieves the migration of a virtual machine with a hybrid storage mode, that is, a storage mode in which the data to be migrated includes both local data and shared data.

Abstract: The present disclosure provides a data storage method and device. The data storage method includes: receiving data by a simulating device from a client operating system; encapsulating the data in a user space of a host system according to a protocol used by a storage server; and sending the encapsulated data to the storage server for storage. The method can realize storing data in the storage server, thereby shortening the I/O path, improving the I/O throughput of a system, reducing the CPU load, and optimizing the system performance.
