Abstract: A first device receives a migration instruction sent by a second device and creates a target virtual machine of a to-be-migrated virtual machine that is in the first device. Then, the first device receives a memory bitmap of the to-be-migrated virtual machine from the second device, where the memory bitmap may indicate whether data of each memory unit in a memory of the to-be-migrated virtual machine is stored in a non-volatile memory or a volatile memory. In a virtual machine migration process, the first device stores, based on the memory bitmap, data in the memory of the to-be-migrated virtual machine into a volatile memory and a non-volatile memory of the target virtual machine.

Abstract: A memory setting method and apparatus the method including obtaining, by a processor that is in a non-uniform memory access architecture (NUMA) system and that has at least two memories, performance of the at least two memories upon the processor starting, and setting, based on the performance of the at least two memories, at least one of the at least two memories as a local memory, and setting, based on the performance, at least one of the at least two memories as a remote memory, where performance of the local memory is better than performance of the remote memory.
