Boot repairing method for virtual machine and server

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...

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.
