Virtualized cluster system, resource allocation method and management node

Abstract

Embodiments of the present invention provide a virtualized cluster system, a resource allocation method, and a management node. The resource allocation method of the present invention includes: calculating the resource allocation value of the virtual machine in the virtual cluster system according to the value of the resource parameter of the virtual machine in the virtual cluster system, and determining the resource pool on the computing node running the virtual machine , according to the resource allocation value of the virtual machine and the structure of the resource pool mapped on the computing node, determine the resource allocation value of the resource pool mapped on the computing node, and send the resource allocation value of the mapped resource pool and the resource allocation value mapped on the computing node to the computing node The structure of the resource pool, so that the computing node allocates resources for the virtual machines running on the computing node according to the resource allocation value of the mapped resource pool and the structure of the resource pool. In the embodiment of the present invention, when the performance of the virtual machine changes frequently, the resources allocated to the virtual machine can be adjusted in time to meet the resource requirements of the virtual machine and ensure the service performance of the virtual machine.

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...
