Memory virtualization-based snapshot boot apparatus and method

摘要

The present invention relates to a memory virtualization-based snapshot boot apparatus and method. The memory virtualization-based snapshot boot apparatus includes hardware unit including a processor, memory, and storage, the storage storing status information corresponding to an operating system, and a Virtual Machine Monitor (VMM) operated by the processor and configured to operate the operating system by loading the status information into the memory. In accordance with the present invention, technology for loading only a part of a snapshot image and booting a system is implemented using virtualization technology, thus shortening the booting time of the system.

主权项

1. A memory virtualization-based snapshot boot apparatus, comprising:
a hardware unit including a processor, a memory, and a storage, the storage storing status information corresponding to an operating system; and a Virtual Machine Monitor (VMM) operated by the processor and configured to operate the operating system by loading the status information into the memory, wherein the status information is stored as a snapshot image, the snapshot image being classified and stored depending on types of the status information, wherein the virtual machine monitor comprises a determination unit for determining whether a header of the snapshot image is valid or not and a loading unit for, if it is determined by the determination unit that the snapshot image header is valid, loading the snapshot image, and wherein the loading unit classifies and loads the snapshot image depending on the types of the status information.
