Method and device for allocating CPU resources of virtual machine

Abstract

The invention discloses a method and a device for allocating CPU resources of a virtual machine. The method comprises the following steps of: monitoring operating conditions of all virtual machines in the current period to obtain the monitoring information which at least includes CPU resource utilization rates of all virtual machines in the current period and the throughputs applied to all virtual machines in the current period; according to the monitoring information, performing feedback adjustment on CPU resource request of all virtual machines in the next period by taking the target CPU resource utilization rate of all virtual machines and the target throughputs applied to all virtual machines as a target; according to the CPU resource request of all virtual machines, deciding the CPU resource allocations of all virtual machines in the next period on a virtual machine management control layer; and according to the CPU resource allocations of all virtual machines, allocating CPU resources for all virtual machines. The method adopts a dynamic mode to allocate CPU resources for all virtual machines, so that all virtual machines on one physical node can be coordinated to share the CPU resources.

Description

technical field [0001] The present invention relates to the technical field of virtual machines, in particular to a virtual machine CPU resource allocation method and device. Background technique [0002] In the data center, in order to ensure the stable power supply environment, suitable temperature and humidity control and network bandwidth conditions required for server operation, a large number of servers need to be managed in a centralized and unified manner. Traditional server application deployment often takes the form of a dedicated server (Dedicated server). In this way, in order to prevent multiple applications deployed on the same physical node from interfering with each other, generally a physical node only deploys a single application or a component of an application. However, this method will inevitably lead to adverse consequences such as low utilization of hardware resources, excessive purchase of hardware resources, etc., and also increases the cost of mana...

Problems solved by technology

[0006] However, the current static resource allocation method cannot meet the application requirements

Because to ensure the service quality of the application, it must be allocated according to the maximum demand of the application. On the one hand, the maximum demand of the application is unpredictable, and on the other hand, it still has to face the problem of low resource utilization.
