Problems solved by technology

At this point, if the main domain simply puts the data container E When a new virtual storage device is formed between data container C and data container D, problems will arise because the partition information recorded on the original virtual storage device is consistent with the partition structure on the original virtual storage device Yes, but it is not consistent with the partition structure of the regenerated virtual storage devi

Abstract

The invention relates to a computer system construction of a virtual storage device based on partition management, which comprises a computer hardware device and a software unit operated on the computer hardware device. The software unit comprises a primary domain and a secondary domain, the primary domain is directly operated on the computer hardware device, and the secondary domain contains a virtual machine monitor which supports a virtual machine containing the virtual storage device. The secondary domain is operated on a virtual machine supported by the virtual machine monitor of the primary domain to access to the virtual storage device. The invention has the advantages that the primary domain of the system is provided with a virtual storage device construction module which is responsible of constructing the virtual storage device by a data container and/or data container segments which are managed by the primary domain, and the virtual storage device construction module sets partition information for the virtual storage device so as to meet management regulations. The invention also provides a construction method of virtual storage device based on partition management. The invention can flexibly construct the virtual storage device, thereby increasing the manageability of the secondary domain.

Description

technical field [0001] The invention relates to a computer virtualization technology, specifically, to a computer system and method for constructing a virtual storage device based on partition management, and belongs to the technical field of computer storage virtualization. Background technique [0002] At present, the hardware of modern computers widely used in the industry includes a central processing unit (Central Processing Unit), a memory (Main Memory) and a storage device (Storage). As a kind of modern computer, the computer adopting x86 central processing unit develops very rapidly, and x86 central processing unit has developed to 64 bits (being called as x86_64 or x64) now. This type of computer has already broken through the scope of personal use, and has entered industrial fields such as data centers and industrial control in large numbers. Because these computers use x86 ( x64) architecture CPU, people Such computers are called x86 computers. The present i...
