Abstract

The invention provides a method and equipment for scheduling a virtual machine. The method comprises the following steps of: determining a multiplexing ratio of a source resource pool, wherein the source resource pool is a heavy load resource pool on a source physical computational node, and the multiplexing ratio is the ratio of the number of VCPUs (virtual central processing units) to the number of physical kernels; selecting an objective resource pool, wherein the objective resource pool is a resource pool on an objective physical computational node, the multiplexing ratio of the objective resource pool is identical to the multiplexing ratio of the source resource pool, and the objective resource pool has sufficient set resources; and migrating the virtual machine on the source resource pool to the objective resource pool. With the adoption of the embodiment of the invention, the service quality of a CPU (central processing unit) when the virtual machine is scheduled is ensured.

Description

Technical field [0001] The present invention relates to communication technology, and in particular to a virtual machine scheduling method and equipment. Background technique [0002] The long-term operation of various services in the network will cause the uneven load of the physical computing nodes in the cloud computing resource pool, resulting in reduced business efficiency and waste of resources. Load balancing scheduling is required to balance the load of each physical computing node. At present, the most commonly used load balancing technology is load balancing scheduling based on the occupancy rate of the central processing unit (CPU) of the physical computing node. In this scheduling mode, the resource management system regularly collects the CPU occupancy rate of each physical computing node, and determines whether the physical computing node is overloaded by comparing the CPU occupancy rate of each physical computing node and the preset reload threshold to trigger the ...
