Embodiment Construction

[0071] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0072] figure 1 It is a system architecture diagram of an aggregated virtualization application in an embodiment of the present invention. As shown in the figure, the system includes: multiple hosts, and the processor on each host can support the interception of memory access sensitive instructions, so as to realize the capture of commands in each host All access to the shared memory and guarantee the correctness of the memory data. The processor of e...

Abstract

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.

Description

technical field [0001] The embodiments of the present invention relate to the field of computers, and in particular to a method, device and system for realizing memory sharing in aggregation virtualization. Background technique [0002] At present, aggregated virtualization technology is widely used in large-scale server applications. Multiple independent servers are interconnected through physical connections, and aggregated virtualization technology is used to make multiple servers appear as one server to the outside world. After using aggregated virtualization technology, resources such as Central Processing Unit (CPU for short), memory (Memory for short), and InputOutput (IO for short) devices of multiple servers can form a resource pool for unified external presentation. It is used for high-performance computing and cloud computing infrastructure. [0003] In a virtualization application scenario, each server runs virtual machine manager (Hypervisor) software, which i...
