Problems solved by technology

[0005] The inventor found through research that since the operating system of the virtual machine is updated in windows server 2008, the boot partition and system partition of the virtual machine are not in the same disk partition, and the system partition is usually a hidden partition, which causes the server deployed on the physical machine to be converted into a virtual machine After that, the system partition cannot be virtualized, causing the system to fail to start
At the same time, the BCD in the physical machine is hidden, and the virtual machine cannot find the BCD during the virtual machine startup process, which also makes the virtual machine fail to start.

Embodiment Construction

[0043] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] Such as figure 1 As shown, the embodiment of the present invention provides a virtual machine startup repair method, which may include:

[0045] S001. After the virtual machine is started, it is judged whether a repair instruction is received within a preset time period. If so, step S002 to step S004 are executed sequentially. Otherwise, other processing can be performed, such as: controlling the virtual machine to start nor...

Abstract

The embodiment of the invention provides a boot repairing method for a virtual machine and a server. The method comprises the steps of after the virtual machine begins to boot, reestablishing system partitions of the virtual machine into a disk where a boot partition of the virtual machine is located according to a repairing command; and reestablishing boot configuration data of the virtual machine according to a catalogue where the reestablished system partitions are located. According to the boot repairing method for the virtual machine and the server, because the system partitions of the virtual machine are reestablished into the disk where the boot partition of the virtual machine is located, the system partition virtualization can be realized to guarantee successful system boot; because the BCD is reestablished according to the catalogue where the reestablished system partition is located, the virtual machine is enabled to find the reestablished BCD, and the virtual machine is guided to start according to the reestablished system partitions by use of the BCD. Therefore, the problem of boot failure after a physical server is converted into the virtual machine is solved.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a virtual machine start-up repair method and a server. Background technique [0002] Currently, with the popularization of virtualization, more and more servers adopt virtualization. Servers previously deployed on physical machines also need to be converted to virtual machines. [0003] The startup process of the virtual machine is: [0004] (1), system power up, (2), load system partition, (3), load system partition BCD, (4), guide system to boot partition, (5), load the operating system directory of boot partition, (6) ), enter the operating system. [0005] The inventor found through research that since the operating system of the virtual machine is updated in windows server 2008, the boot partition and system partition of the virtual machine are not in the same disk partition, and the system partition is usually a hidden partition, which causes the server deployed on the p...
