Real-time virtual machine deployment method

Abstract

The invention discloses a real-time virtual machine deployment method; the method includes, firstly, initializing a storage domain, a storage pool and time zone information of a virtual machine; updating same to a static data table of the virtual machine; verifying starting parameters of the virtual machine; when the starting parameters of the virtual machine pass verification, starting the virtual machine; and allocating real-time computing resources of the virtual machine, including a CPU (Central Processing Unit), a memory and a network card, assembling a parameter xml (Extensible Markup Language) file containing the computing resources needing to be allocated, sending the parameter xml file to the host, and finally completing isolation and allocation of the computing resources, completing deployment, starting the virtual machine and returning a deployment result and the current state of the virtual machine by the host. According to the invention, whether the real-time resources meet the deployment requirement or not can be automatically verified, the deployment environment is provided, the real-time resources are allocated to the real-time virtual machine, multiple operation steps are omitted while the real-time performance of the real-time virtual machine is guaranteed, and the method has a very good practical effect.

Description

technical field [0001] The invention relates to the field of virtual machine deployment in cloud computing, in particular to a method for real-time virtual machine deployment. Background technique [0002] Existing ordinary virtual machine deployments can over-allocate CPUs without binding CPUs. In this way, other threads will occupy the CPU, causing CPU scheduling delays, and virtual machines directly steal time from each other, affecting CPU scheduling delays, resulting in the entire virtual machine The delay of the machine becomes higher, so it is not suitable for application scenarios with strict delay requirements. [0003] In addition, the existing deployment of ordinary virtual machines can over-allocate memory, which will cause memory to be swapped to the host, and QEMU memory to be swapped, causing delays and affecting real-time performance. Contents of the invention [0004] The technical problem solved by the present invention is: to overcome the deficiencies o...
