Embodiment Construction

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

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

[0058] The controller is a node that manages all virtual machines in a cluster, and the controller is connected to all hosting hosts in the cluster. A virtual machine is a virtualized computer system hosted on a host computer. Host hosts are computers in the physical sense. A host host can be divided into multiple virtual machines. The hosting host can perceive behaviors such as shutdown and startup of the virtual machine hosted on the host host. Wherein, when the start-up state and the downtime state of the virtual machine are perceived by the hosting host, the start-up state and the downtime state of the virtual machine are regarded as special states of the virtual machine, and a notification of ...

Abstract

Disclosed are a method and system for restoring a virtual machine, and a controller, a server and a guest host. The method includes: a server receiving a first transfer instruction from a controller, the first transfer instruction being used for instructing the server to pre-copy memory data of a mirror image of a virtual machine to a guest host once; and the server pre-copying the memory data of the mirror image of the virtual machine to the guest host once according to the first transfer instruction, and restoring the virtual machine at the guest host. In this way, the present invention can effectively improve the starting time of a virtual machine.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a virtual machine restoration method, system, controller, server, and hosting host. Background technique [0002] A virtual machine refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. After entering the operating system of the virtual machine, all operations are carried out in this new independent virtual system, which can independently install and run software, save data, and have its own independent desktop without any impact on the real system. Wherein, one or more virtual machines can be virtualized on one physical computer. [0003] There are three main ways to start a virtual machine, namely: CD-ROM boot, hard disk boot, and network boot. CD-ROM boot means that the virtual machine starts from the CD-ROM. Network startup means that the virtual machine is not ...
