Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described:

[0026] See figure 1 , the present invention relates to a memory control method of a physical machine with multi-cloud hosts, and a preferred implementation thereof includes the following steps:

[0027] Step S1: Allocate corresponding memory pages to each cloud host, and set the QOS (Quality of Service, service quality) level value identification of the corresponding cloud host on each memory page;

[0028] Step S2: Obtain the usage rate of the total physical memory;

[0029] Step S3: Determine whether the usage rate of the total physical memory exceeds the upper threshold, if yes, execute step S4, if not, return to execute step S2; and

[0030] Step S4: move the used memory corresponding to each cloud host from the physical memory to the swap partition step by step according to the QOS level value identification of each memory page from low to hi...

Abstract

A memory control method of a physical computer with multi-cloud hosts comprises the following steps: S1, allocating corresponding memory pages for each cloud host, and setting QOS rank value identifications corresponding to cloud hosts in each memory page; S2, obtaining the total physical memory utilization rate; S3, determining whether the total physical memory utilization rate exceeds an upper limit threshold value or not; if yes, executing step4; if not, returning to step2; S4, gradually transferring used memory corresponding to each cloud host from the physical memory to an exchange partition according to a rising order of the QOS rank value identifications in each memory page. The method and system can gradually transfer memories of the cloud hosts with different QOS rank values in the rising order, thus preferably ensuring memory usage of the cloud hosts with high level, and preventing system avalanche caused by overloading.

Description

technical field [0001] The invention relates to a memory control method and system of a physical machine with multi-cloud hosts. Background technique [0002] The cloud host is a group of cluster hosts that virtualize multiple parts similar to independent hosts. Each host in the cluster has a mirror image of the cloud host, which greatly improves the security and stability of the virtual host. [0003] At present, multiple cloud hosts on a physical machine use the resources of the host machine in a balanced manner to perform calculations according to their respective configurations. When the memory usage of the physical machine is close to the bottleneck, the system is prone to avalanches. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention aims to provide a memory control method of a physical machine with multi-cloud hosts that can solve the above-mentioned technical problems. [0005] To achieve the above object, the pre...
