Example Embodiment

[0056] See figure 1 , figure 1 It is a flowchart of the first embodiment of the method for restoring a virtual machine of the present invention. As shown in the figure, the method includes:

[0057] Step S101: the controller receives a start notification for starting the virtual machine;

[0058] The controller is a node that manages all virtual machines in a cluster, and the controller is connected to all host machines in the cluster. A virtual machine is a virtualized computer system hosted on a host machine. The host computer is a computer in the physical sense. A host machine can be divided into multiple virtual machines. The host machine can perceive the shutdown and startup behaviors of the virtual machine hosted on the host machine. Among them, when the host computer perceives the startup state and down state of the virtual machine, the startup state and down state of the virtual machine are regarded as the special state of the virtual machine, and the special state noti...

Abstract

The invention discloses a method and system for restoring a virtual machine, a controller, a server and a hosting host. The method comprises the steps that the server receives a first migration instruction from the controller, and the first migration instruction is used for indicating the server to pre-copy stored data of a mirror image of the virtual machine to the hosting host at single time; the server pre-copies the stored data of the mirror image of the virtual machine to the hosting host at single time according to the first migration instruction and restores the virtual machine in the hosting host. Through the mode, the starting time of the virtual machine can be effectively shortened.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a method, system, controller, server, and host computer for restoring a virtual machine. Background technique [0002] Virtual machine refers to a complete computer system with complete hardware system functions that is simulated by software and runs in a completely isolated environment. After entering the operating system of the virtual machine, all operations are carried out in this brand new independent virtual system. You can install and run software independently, save data, and have your own independent desktop without any impact on the real system. Among them, one or more virtual machines can be virtualized on one physical computer. [0003] There are three main ways to start a virtual machine: CD-ROM boot, hard disk boot, and network boot. CD-ROM booting means that the virtual machine is booted from the CD-ROM drive. Network boot means that the virtual machine is no...
