Resource reservation method and apparatus for virtual machine cluster system

Abstract

The invention discloses a resource reservation method and apparatus for a virtual machine cluster system. The method comprises the steps of monitoring a CPU resource usage status of a virtual machine system when it is monitored that the virtual machine system is started; and when it is monitored that CPU resources needed to be reserved exist, binding the CPU resources needed to be reserved to a reserved CPU logic core in a resource pool, thereby scheduling the CPU resources on the CPU logic core in the resource pool. According to the resource reservation method and apparatus for the virtual machine cluster system, related resources of a key virtual machine can be reserved, and when resource seizing occurs in the virtual machine cluster system, the key virtual machine can schedule the reserved related resources from the reserved CPU logic core, so that the key virtual machine has available resources and normal operation of the key virtual machine is ensured.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a method and device for reserving resources of a virtual machine cluster system. Background technique [0002] With the rapid development of computer technology and the Internet, operating system virtualization technology has become increasingly mature. The virtualization system allows multiple operating systems to run concurrently on the same physical host, using the same hardware, without affecting each other. Clusters can be composed of multiple virtual machines. At present, cluster systems have gradually become the focus of the computer industry due to their low cost, powerful computing capabilities, and sound fault-tolerant mechanisms. However, due to differences in the application programs running in the virtual machines or the differences in the performance of host physical hosts, resource load imbalance may occur during the operation of the cluster system. [...

However, due to the differences in the applications running in the virtual machine or the performance of the host physical host, resource load imbalance may occur during the operation of the cluster system

[0003] The resource allocation in the cluster system can be shared, which is the advantage of the cluster system, but when the system load is relatively high, it will also cause CPU resources and memo...
