Embodiment Construction

[0051] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0052]The main solution of the embodiment of the present invention is: under the first operating system, obtain the physical disk sector information occupied by the pre-created disk file, save it in the configuration file of the first operating system; install the second operating system The boot program of the second operating system releases the boot file and the kernel of the second operating system to the system disk of the first operating system; when receiving a trigger operation based on the boot program under the first operating system, the kernel is run and from The boot file is obtained from the system disk; the sector information of the disk file is obtained from the configuration file through the boot file, and a virtual disk is generated according to the sector information, so as to complete all steps thro...

Abstract

The invention discloses an operating system coexistence method, comprising: in a first operating system, obtaining physical disk sector information occupied by a pre-created disk file and storing the physical disk sector information in a configuration file of the first operating system; installing a boot program of a second operating system and releasing the boot file and a kernel of the second operating system to a system disk of the first operating system; when receiving a boot program based trigger operation in the first operating system, running the kernel to obtain the boot file from the system disk; and obtaining the sector information of the disk file from the configuration file according to the boot file, generating a virtual disk according to the sector information, and finishing reading and writing of the second operating system through the virtual disk. The invention furthermore discloses an operating system coexistence apparatus. According to the operating system coexistence method and apparatus, the operating system coexistence complexity is lowered, the disk partition layout of an original system is not destroyed, and the system coexistence effect is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for coexistence of operating systems. Background technique [0002] At present, users want to migrate the current business system to the virtualization platform, and usually use P2V (Physical to virtual, conceptual physical to virtual) migration to migrate the business system to the virtualization platform through the network. The problem that exists in this way is that the data volume of the business system If it is relatively large, the migration process will take a long time, causing business interruption for too long. Moreover, new data generated after migration cannot be synchronized to the original physical system. When users use the virtualization platform for the first time, they are limited by the server hardware. In order to verify the stability of the virtualization platform and ensure data security, they hope to have a way to directly coexist wi...
