Problems solved by technology

[0003] The system restoration technology in the prior art needs to use the previous backup files to restore the operating system on the hard disk. After the restoration is completed, the computer needs to be restarted, so the system restoration time is relatively long and the efficiency is low.

Embodiment Construction

[0040] The embodiment of the present invention proposes a method for quickly restoring a guest operating system by using a virtual machine technology. The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0041] Such as figure 1 As shown, the system restoration method based on the guest operating system described in the embodiment of the present invention is based on virtual machine technology and is applied to a virtual machine system installed with a guest operating system. The method specifically includes the following steps:

[0042] Step 11, when creating a hard disk for the guest operating system, configure an incremental file system, and map the incremental file of the incremental file system to the hard disk of the guest operating system.

[0043] Here, when the hard disk is created for the guest operating system, the incremental file mapping the incremental file system of the underlying vir...

Abstract

The invention provides a system restore method, a virtual machine managing device and a system based on a client operating system. The method comprises the following steps: receiving a restore command aiming at the client operating system; suspending the operation of the client operating system after receiving the restore command, wherein the restore command comprises a preset restore point; determining a first memory snapshot and a first incremental file corresponding to the restore point, wherein the first memory snapshot is a memory snapshot of the client operating system created at the time of setting the restore point, and the first incremental file is the incremental file mapped into a first hard disc at the time of setting the restore point; and remapping the first incremental file into the first hard disc, and executing the snapshot restore according to the first memory snapshot. According to the invention, the system can be fast restored.

Description

technical field [0001] The invention relates to the technical field of virtual machines, in particular to a system restoration method based on a guest operating system, a virtual machine manager and a system. Background technique [0002] In some unexpected cases, the computer's operating system will enter an unexpected state because the user has installed some software or performed certain operations. At this time, it is often necessary to restore the operating system using the previous system backup , that is, restore to a backup state made at a previous point in time. [0003] The system restoration technology in the prior art needs to use the previous backup files to restore the operating system on the hard disk. After the restoration is completed, the computer needs to be restarted, so the system restoration time is relatively long and the efficiency is low. Contents of the invention [0004] The technical problem to be solved by the embodiment of the present inventi...
