Method for dynamic allocation of virtual machines for cloud computing system

Abstract

The invention provides a method for dynamic allocation of virtual machines for a cloud computing system. The method includes: virtualizing physical resources of the cloud computing system into a batch of virtual machines and composing the same into one or a plurality of virtual machine pools; establishing a virtual machine management module used for managing and scheduling the cloud computing system of the virtual machines in the virtual machine pool, and setting a user information database used for storing user information of a user having the right to access to the virtual machine pool into the virtual machine management module; the virtual machine management module responding to virtual machine allocation requests transmitted by the user to the virtual machine management module, performing authentication on the user, and then selecting one virtual machine from the virtual machine pool and allocating the same to the user after the user passes the authentication; after the user exits, the virtual machine management module retrieving the virtual machine, wherein the virtual machine is reset for next allocation. Allocation of the virtual machines is performed through the virtual machines well established in the virtual machine pool, so that response time in virtual machine allocation is shortened, and risk of occurrence of boot storm is lowered.

Description

technical field [0001] The invention relates to the application fields of computer virtualization, cloud computing and desktop virtualization, and in particular relates to a method for dynamically allocating virtual machines in a cloud computing system. Background technique [0002] "Virtual machine" refers to any virtual machine operating environment running on the top layer of the virtualization layer (hypervisor layer) provided by virtualization solutions, such as VMware ESX / ESXi. "Virtual machine template" refers to the operating system running on the virtual machine and its integrated software, applications and other overall environment, which is similar to the system installation CD used by traditional computers to install the operating system. The virtual machine "inactive" means that the created virtual machine is suspended and placed in a dormant state. Suspended virtual machines consume no computing resources and can be quickly restored to a powered-on state for u...

AI Technical Summary

Problems solved by technology

When assigning a virtual machine to a user, a new virtual machine needs to be created, and it takes a long time to create a new virtual machine, resulting in a long allocation response time;

[0006] 2. There is a high risk of startup storms during batch allocation

Creating virtual machines in batches will generate a large number of intensive read and write operations, so the risk of a startup storm is extremely high;

[0007] 3. For application scenarios with a large user base but a small number of concurrency, it will cause serious waste of resources

However, in the traditional desktop allocation model, the virtual machine of the remote office worker continues to occupy computing resources

[0008] 4. Auditing is difficult for data centers with limited resources

In addition, since each virtual machine has one virtual machine, when the resource is fully loaded, the virtual machine must be deleted and rebuilt if the owner is to be replaced, resulting in low resource reuse rate and difficult reuse.
