Problems solved by technology

[0004] The solution in Patent Document 1 achieves computing resources and scheduling. However, this solution uses a single virtual machine scheduler, and needs to use a box-packing algorithm to calculate the resources of the entire system before unified scheduling. It is d

Example

[0191] Example 1: The CPU load on the physical server is too large, and the scheduling demand manager 15a sends a virtual machine 14 migration request to the three scheduling demand managers 15b, 15c, and 15d with the smallest network delay, requesting to migrate out 30% of the CPU load . When the scheduling demand manager 15b receives a query whether to accept the scheduling of the virtual machine from the neighboring scheduling demand manager 15a, it judges whether to accept the scheduling of the virtual machine according to the physical server load information obtained from the physical machine monitor, The judgment result is sent to the adjacent scheduling demand manager 15a. For example, if the scheduling demand manager 15b determines that the CPU load of the migration amount is 30% or more, it determines that the scheduling of the virtual machine is accepted. The operation of the scheduling demand managers 15c and 15d is the same as that of the scheduling demand manager...

Abstract

The invention relates to a virtual machine dispatcher, a dispatching demand manager and method and a virtual machine dispatching system. A virtual machine dispatching method is provided. The method is characterized by comprising the following steps that a dispatching requirement from a virtual machine of the dispatching demand manager is monitored, it is judged whether the dispatching requirement comprises dispatching resolution information which is reached by the dispatching demand manager and an adjacent dispatching demand manager or not, under the condition that the dispatching requirement comprises dispatching resolution information which is reached by the dispatching demand manager and the adjacent dispatching demand manager, a dispatching command is sent to the dispatching demand manager and the adjacent dispatching demand manager, and under the condition that a dispatching resolution is reached, the dispatching requirement further comprises information relevant to the adjacent dispatching demand manager.

Description

technical field [0001] The present invention relates to the fields of distributed systems and computer networks, and more specifically, the present invention relates to a virtual machine scheduler, a scheduling demand manager and its method, and a virtual machine scheduling system. Background technique [0002] In recent years, cloud computing technology has developed vigorously. Cloud computing technology has improved the utilization rate of resources (such as hardware resources) while reducing costs, and has performed well in supporting massive data analysis, storage, search and disaster recovery. At the same time, the platform (cloud platform) based on cloud computing technology has good scalability and load balancing capabilities. However, the establishment of a cloud platform also has high requirements for technology, and there are still many tasks to be completed. For example, how to schedule system resources to improve resource utilization and balance load is a thorn...
