Embodiment Construction

[0022] The present invention is further described below in conjunction with accompanying drawing.

[0023] Such as figure 1 , 2 , 3, and 4, a method for virtual machine HA in an OpenStack-based private cloud comprises the following steps:

[0024] 1) Make a virtual machine template injected into the agent (agent service);

[0025] a. Create a virtual machine corresponding to the operating system using a common image file;

[0026] b. Log in to the created virtual machine and deploy the agent service to the virtual machine;

[0027] c. Make the above virtual machine into a mirror image, and the virtual machines that need to implement the HA function are all created using this mirror template;

[0028] 2) Start the agent agent

[0029] When creating a vlan under the network, start the proxy agent in the DHCP agent process. The agent in the virtual machine will report the business network of the virtual machine in real time, whether the storage network is normal, and if an ...

Abstract

Provided is an OpenStack-based virtual machine HA method in a private cloud. A private cloud platform accesses a shared memory through a cinder, and all computing nodes of a cloud host related configuration file are placed in the same shared directory. By managing a virtual machine network through neutron, all virtual machines can be in communication with their own DHCP agents. By monitoring a status of a service network or a storage network of the virtual machines on the computing nodes, the HA can be accurately and timely triggered. A UUID of the virtual machine can be reached by sharing thecloud host related configuration file and a system disk. Configuration, IP and storage data are exactly the same as before. It is ensured that the successful migration does not affect the performanceof virtual machines under other projects. At the same time we also meet the additional needs of users, the users can specify which virtual machines support a HA function. Only these virtual machinesare automatically migrated.

Description

technical field [0001] The present invention relates to a virtual machine HA method in a private cloud based on OpenStack, and specifically relates to a cloud computing and virtualization technology, which virtualizes a plurality of logical computing resources, network resources, and storage resources from physical IT resources to facilitate A method for users to automate the management and operation and maintenance of large-scale data centers. Background technique [0002] OpenStack is an open source cloud computing management platform project that provides a cloud computing management platform that is simple to implement, scalable, rich, and standardized. As the de facto standard of cloud computing IAAS layer, Openstack has been widely used in various industries. But so far Openstack does not have a complete virtual machine HA solution. When some applications that require reliability requirements are deployed on Openstack, if the underlying virtualization software fails,...
