Claim:
1. A virtual machine migration management method, wherein the method comprises: calculating a migration duration time required for migrating a to-be-migrated virtual machine from a source computing node to a destination computing node according to an allocated memory size, a memory change rate, or a migration network bandwidth of the to-be-migrated virtual machine; separately acquiring a current available migration duration time of the source computing node and a current available migration duration time of the destination computing node; comparing the current available migration duration time of the source computing node and the current available migration duration time of the destination computing node to the migration duration time; migrating the to-be-migrated virtual machine from the source computing node to the destination computing node if both the current available migration duration time of the source computing node and the current available migration duration time of the destination computing node are greater than the migration duration time; and subtracting the migration duration time from the current available migration duration time of the source computing node, and subtracting the migration duration time from the current available migration duration time of the destination computing node, wherein the calculating, according to the allocated memory size, the memory change rate, or the migration network bandwidth of the to-be-migrated virtual machine, migration duration time required for migrating the to-be-migrated virtual machine from a source computing node to a destination computing node comprises: calculating migration duration time MTV
