Embodiment 1

[0025] A method for avoiding a single point of failure of oVirt cloud platform management node, including on a physical machine: installing a host operating system, configuring host network and storage, creating a host system environment, creating a management node virtual machine, and creating oVirt-engine management services.

[0026] The installation of the host operating system: install the centos7 operating system on the physical machine, and choose to install the minimal centos system here.

[0027] The configuration of the host machine network and storage: add the repo source of oVirt to create the host system environment and access external resources when creating oVirt-engine; configure the storage nfs service at the same time to provide the iso domain and export domain of oVirt.

Embodiment 2

[0029] A method for avoiding a single point of failure of oVirt cloud platform management node as described in Embodiment 1, the difference is that the creation of the host system environment: use the management node virtual machine provided by oVirt to create a support instruction oVirt-hosted-engine-setup Create a host system environment.

Embodiment 3

[0031] A method for avoiding a single point of failure of oVirt cloud platform management node as described in Embodiment 2, the difference is that in the process of creating the host system environment, use the pre-provided NFS service configuration storage, and specify the full name of the host system Domain name FQDN, the FQDN must be consistent with the configuration of the virtual machine where oVirt-engine is installed; at the same time, upload the system installation image ISO to the host system to provide the system installation image for creating the management node virtual machine.

Abstract

A method for avoiding a single point of failure (SPOF) of oVirt cloud platform engines is characterized in that the engines, which are originally deployed on physical servers, are deployed in virtual machines of nodes, and the virtual machines are configured to be highly available; and when a failure occurs to the engines, migration of engine virtual machines is automatically triggered, so that high stability of an entire oVirt cloud platform system is ensured. Compared with the traditional distributed engine deployment method, the method provided by the invention has the advantages that the number of the applied physical servers is greatly reduced, and a communication process among the multiple servers is simplified, so that an entire deployment process is simple and rapid; and the engine virtual machines are provided with the top response level in the system, so that after the physical machines break down, the engine virtual machines can be firstly automatically migrated, the migrated engine virtual machines can automatically take over management tasks, and migration tasks for the other virtual machines are continued, through which the overall efficiency and stability of the system can be greatly improved.

Description

technical field [0001] The invention relates to a method for avoiding a single-point failure of a management node of an oVirt cloud platform, and belongs to the technical field of computer virtualization. Background technique [0002] oVirt is an open source virtualization management platform based on the KVM project. Its main part is mainly composed of computing nodes (Nodes) and management nodes (Engine). The computing nodes provide external computing resources such as CPU and memory, and act as virtual machine managers (Hypervisor). The role of the host, and communicate with the management node through the vdsm service, and form a virtual management platform with the management end overt-engine. The management node manages and controls all resources in the entire oVirt cloud platform, and can access the front end through the webadmin portal for management or the user portal with fine-tuned permissions and functions. [0003] In the traditional oVirt cloud computing envir...
