Memory dynamic adjusting method for cloud desktop host and virtual machine

Abstract

The invention provides a memory dynamic adjusting method for a cloud desktop host and a virtual machine. The method comprises the steps that 1, the memory is monitored, wherein the host memory and virtual machine idle memory condition is monitored; a the memory is adjusted, if the host idle memory is lower than the safety level, the idle memory of the virtual machine is extracted, if the host idle memory is higher than the safety level, the memory is returned to the virtual machine, and finally the host memory and the virtual machine memory are higher than the safety level; an alarm message is sent to a manager. The host memory is monitored, the dynamic adjusting frequency is reduced based on the safety level, and therefore the virtual machine has the sufficient memory to response to the emergency requests; normal running of the virtual machine can be ensured by setting the safety level of the virtual machine memory safety level.

Description

technical field [0001] The present invention relates to the technical field of cloud desktops, in particular to a method for dynamically adjusting the memory of a cloud desktop host and a virtual machine. Background technique [0002] The dynamic adjustment of virtual machine memory plays a vital role in the desktop cloud environment, which directly determines the utilization of memory resources of the server and increases the number of virtual machine instances that can be carried. [0003] In the existing technology, the dynamic adjustment of virtual machine memory has the following defects: [0004] 1. The existing method cannot allow the virtual machine to fully use memory resources when the host physical memory is sufficient; [0005] 2. The safe amount of virtual machine memory is not set to ensure the normal operation of the virtual machine; [0006] 3. After multiple times of dynamically adjusting the memory of the virtual machine, it is still unable to obtain enou...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing method cannot allow the virtual machine to fully use memory resources when the host physical memory is sufficient;

[0005] 2. The safe amount of virtual machine memory is not set to ensure the normal operation of the virtual machine;

[0006] 3. After multiple times of dynamically adjusting the memory of the virtual machine, it is still unable to obtain enough memory to trigger a warning

[0007] For example, the Chinese patent "method and device for adjusting virtual machine memory" (application number: 201180003694.9), and the Chinese patent "method and system for dynamically adjusting virtual machine memory in a cloud computing environment" (application number: 201310594574.1), the technical points disclosed by both are Adjust the memory of the virtual machine according to the memory usage of the virtual machine, which is not adjusted according to the memory of the host where the virtual machine is located, and does not effectively handle the adjustment failure
