Embodiment 1

[0026] The inventor of the present application proposes an openstack virtual machine memory QOS solution that can be realized by modifying the configuration when creating the virtual machine and combining the interface provided by the virtual machine management tool libvirt for the openstack virtual machine.

[0027] Based on the above ideas, this embodiment provides a method for managing virtual machines in a cloud computing management system, which mainly includes the following operations:

[0028] Constructing a virtual machine using a pre-created flavor, wherein the pre-created flavor at least includes a virtual machine memory resource usage limit parameter;

[0029] When the constructed virtual machine is in a competition state, the memory resource of the host is obtained according to the virtual machine memory resource usage limit parameter in the flavor of the virtual machine.

[0030] Wherein, the pre-created flavor includes the parameters required by each clock to bui...

Embodiment 2

[0042] This embodiment provides a cloud computing management system, including the following operations:

[0043] A construction unit, using a pre-created flavor to construct a virtual machine, the pre-created flavor at least including virtual machine memory resource usage restriction information;

[0044] The created flavor can be some existing metadata, or some metadata can be added, as long as it is the flavor required to build the virtual machine, for example, at least including the number of VCPUs, memory size, disk size, etc. of the virtual machine.

[0045] The virtual machine memory resource usage restriction information may include a ratio of memory resources allowed to be used by each virtual machine among all created virtual machines.

[0046] The management unit is configured to allocate the memory resources of each virtual machine according to the virtual machine memory resource usage limitation information in the flavor of each virtual machine in competition when...

Abstract

The invention discloses a cloud-computing management system and a virtual machine management method thereof, and relates to the technical field of openstack (cloud-computing management platform) virtualization. The cloud-computing-management-system virtual machine management method mainly includes the steps that virtual machines are established with pre-established metadata, wherein the pre-established metadata at least comprises virtual-machine-memory-resource use restriction information; when the established virtual machines are in the contention state, memory resources of all the virtual machines are distributed according to the virtual-machine-memory-resource use restriction information in the metadata of all the virtual machines in the contention state. According to the technical scheme, a memory QOS scheme is achieved by changing virtual-machine configuration files in cooperation with a libvirt management tool, achievement is simple and clear, the requirement of the virtual machines for the memory QOS is met, and the flexibility and the working performance of the virtual machines are improved.

Description

technical field [0001] The invention relates to the technical field of openstack (cloud computing management platform) virtualization, in particular to a cloud computing management system and a method for managing virtual machines. Background technique [0002] With the application of virtualization technology more and more widely, in various fields, virtual machines are gradually replacing physical machines to run some businesses. When more and more businesses run on virtual machines, people have more and more requirements for virtual machines. High, including virtual machine configuration, performance, etc. In terms of virtual machine resource configuration, virtual machine memory configuration is very important. When the host resources are sufficient, there is no problem, but when the host resources are tight, it is necessary to prioritize the allocation of host resources to those virtual machines running important services. Memory QOS (Quality of Service) technology is ...
