Virtualized cluster system, resource distributing method and management node

Abstract

The embodiment of the invention provides a virtualized cluster system, a resource distributing method and a management node. The resource distributing method comprises the following steps: calculating the resource distribution value of a virtual machine in the virtualized cluster system according to the value of the resource parameter of the virtual machine in the virtualized cluster system; determining a resource pool operating on a calculating node of the virtual machine; determining the resource distribution value of the resource pool mapped on the calculating node according to the resource distribution value of the virtual machine and the structure of the resource pool mapped on the calculating node; sending the resource distribution value of the mapped resource pool and the structure of the resource pool mapped on the calculating node to the calculating node; using the resource distribution value of the mapped resource pool and the structure of the resource pool as the distributed resource of the virtual machine operated on the calculating node by the calculating node. By the adoption of the implement examples, under the condition of much frequent performance change of the virtual machine, the resource distributed to the virtual machine can be adjusted in time to satisfy the resource requirement of the virtual machine, so that the professional performance of the virtual machine is ensured.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, and in particular to a virtualized cluster system, a resource allocation method and a management node. Background technique [0002] In virtualization technology, by virtualizing physical computing nodes (that is, physical servers), multiple virtual machines (Virtual Machines, VMs for short) can be deployed on a single physical computing node, thereby effectively improving the resource utilization of physical computing nodes. Rate, wherein, a resource pool composed of multiple physical computing nodes deployed with VMs becomes a virtualized cluster system. The cluster integrates the resources (such as CPU resources and memory resources) of all physical computing nodes in the cluster and merges them into the root resource pool corresponding to the cluster. Users can create sub-resource pools of the root resource pool (the root resource pool is its The parent resource p...
