The invention provides a dynamic extensible method for increasing virtual machine resources. An internal storage index client side (1), an internal storage service program (2), an internal storage node pool (3), a storage client side (4), a storage service program (5) and a storage pool (6) are integrated with the high-performance network as a core so that the requirements for dynamically increasing internal storage, storage resources and dynamic transferring of a virtual machine can be met by a system, the internal storage service program can change the internal storage space provided by an internal storage server cluster to be the internal storage pool in a virtual mode, internal storage nodes can be dynamically divided according to the request of the internal storage index client side, and when an unoccupied adjacent internal storage node exists, the internal storage nodes can be combined to meet the dynamic internal storage demands of different client sides. The internal storage service program can operate in a cluster mode, and under a cluster mode, the internal storage pool also needs to record internal storage nodes managed by other internal service programs, and accordingly the client sides can select services from the internal storage service program with many unoccupied internal storage nodes or with a small load.
