MEMORY SHARING METHOD, DEVICE AND SYSTEM IN AGGREGATION VIRTUALIZATION

摘要

An embodiment of the present invention discloses a memory sharing method in aggregation virtualization. The method comprises: a cache coherence processor receiving a memory processing command sent by a virtual machine manager of a host; if the memory processing command is cache state update information, the cache coherence processor updating a local cache coherence catalog according to the cache state update information; or, if the memory processing command is a memory access request of a virtual machine on the host, the cache coherence processor performing cache coherence processing and accessing a memory corresponding to memory address information in the memory access request. A memory processing command is sent to a cache coherence processor through a virtual machine manager of a host, and the cache coherence processing is performed by the cache coherence processor, thereby improving system processing performance, and shortening the memory access time. Embodiments of the present invention also disclose a memory sharing device and system in aggregation virtualization.
