Problems solved by technology

When the API is called for the third time to create VM3, the creation fails because the remaining resources on HostA and HostB cannot satisfy the resources required by VM3.
As a result, the system resource utilization is only 50%
It can be seen that there is a problem of insufficient resource utilization when the management system allocates resources

Abstract

The invention provides a method for distributing resources of a host machine, and a management server. The method comprises the steps of acquiring resource specifications of a plurality of virtual machines required by an application; ranking weights of the plurality of virtual machines according to a ranking rule and the resource specifications of the virtual machines; and applying for distributing the resources of the host machine according to the weights of the virtual machines in an order from big to small. According to the method and the device provided by the invention, the virtual machines required by the application are distributed after being ranked according to the weights in a unified manner, and thus the resource utilization rate of the host machine is greatly improved.

Description

Technical field [0001] The present invention relates to the field of information technology, in particular to a method and device for allocating host machine resources. Background technique [0002] Cloud computing technology realizes the shielding of the underlying resources from the business. The business runs on the virtual machine in the host machine. In the case of multiple host machines and virtual machines, the resource utilization of the host machine is closely related to the allocation algorithm of the virtual machine. [0003] For example, there are two host machines hostA and hostB. Their resource specifications are both 8-core CPU and 8G bytes of memory. Three virtual machines VM1, VM2, and VM3 need to be run on these two hosts, among which VM1 and VM2 are The resource specifications are 4-core CPU and 4G bytes of memory, and the resource specifications of VM3 are 8-core CPU and 8G bytes of memory. Obviously, the allocation method with the highest operating utilizatio...
