Virtual machine system and management method thereof

Abstract

The invention provides a virtual machine system which comprises a plurality of servers, a distributed type file storage device and a virtualization management module. Each server comprises a plurality of virtual machines and a high availability module and mirror image documents of each virtual machine is stored in each server. Copies of the mirror image documents of each virtual machine of each server are stored in the distributed type file storage device. When the high availability module of one server confirms that one or more virtual machines break down and the mirror image documents stored locally cannot locally start the broken virtual machine, the virtualization management module calls the high availability module in another server of the plurality of servers to call the copies, stored in the distributed type file storage device, of the mirror image files of the corresponding virtual machine so that the broken virtual machine can be recovered on the another server. The virtual machine system guarantees operation efficiency of the virtual machines and reduces cost through the distributed type file storage device with low price.

Description

technical field [0001] This application relates to an IT system and its management method, in particular to a virtual machine system and its management method Background technique [0002] Through X86 virtualization (hereinafter referred to as: virtualization) technology, multiple independent virtual machines can be constructed in a general-purpose X86 server (hereinafter referred to as: server), and the virtual machines share the server's CPU, memory, I / O and other resources. A resource-sharing virtual machine pool can be constructed through virtualization technology, which helps to realize the integration of IT systems. Generally, virtualization products include two parts: a super monitoring unit (Hypervisor) and a virtualization management system. The super monitoring unit is the control layer between the physical server and the virtual machine, which realizes the abstraction and resource isolation of the physical server resources, and controls the operation of the uppe...

Problems solved by technology

However, this solution relies on centralized storage to store virtual machine image files and run virtual machines, but there are problems such as high implementation costs, complex networking, and poor I / O performance that affect the operating efficiency of virtual machines.
