Embodiment Construction

[0027] There are multiple implementations of the present invention, here will be based on the KVM virtualization implementation as an example to illustrate one of the implementation methods, such as figure 1 , 2 As shown, the specific implementation process is as follows:

[0028] 1. Set the SSD path in the background configuration file

[0029] #SSDPATH= / sdb / ssdcache /

[0030] 2. Create a virtual machine through the cloud platform management terminal

[0031]

[0032] 3. Read the configuration file SSD path in the background

[0033]

[0034] 4. Check whether the specified SSD directory exists in the created virtual machine image cache. If it exists, perform step 6, otherwise execute in sequence

[0035]

[0036]

[0037] 5. Copy the image cache to the specified SSD

[0038]

[0039] 6. Create a virtual machine according to the image cahce path

Abstract

The invention relates to the field of cloud computing management, in particular relates to a method for improving batch power-on / power off speed of virtual machines. The method comprises the following steps: firstly setting a SSD path at a background configuration file; secondly, creating a virtual machine through a cloud platform management terminal; and then reading the configuration file SSD path at the background; checking a mirror image cache for creating the virtual machine has an appointed SSD category, if not, copying the mirror image cache to an appointed SSD; and finally creating the virtual machine according to the mirror image cache path. Through the adoption of the method disclosed by the invention, the cost is saved; through the adoption of the mirror image snapshot technology, only the mirror image cache part disk adopts the SSD, and others adopt the general storage, so that the storage cost is greatly saved; the computing resource usage rate is improved, the virtual machine number capable of being supported by a single physic server cannot be reduced through the bottleneck of the storage; the method can be used for improving batch power-on / power off speed of the virtual machines.

Description

technical field [0001] The invention relates to the field of cloud computing management, in particular to a method for increasing the batch startup and shutdown speed of virtual machines. Background technique [0002] In the cloud computing environment, the performance of the computer's main accessories such as CPU, memory, and graphics card has been improved rapidly. Now a high-performance server can support the creation of more and more virtual machines, and the corresponding disk system Performance is becoming more and more the bottleneck of the performance improvement of the entire system, which leads to slower and slower batch startup and shutdown speeds of virtual machines. Generally, the following methods are used to solve this situation: [0003] 1. The hard disk adopts SSD, which directly improves the IO read and write speed to meet the requirements of batch operations. [0004] 2. Reduce the number of virtual machines on a single physical server and sacrifice reso...
