Abstract

The invention relates to an I / O resource scheduling model for a distributed virtual machine monitor. The model is implemented by the following four steps: 1, detecting a physical resource stage; 2, establishing a global virtual I / O bitmap; 3, processing I / O instructions; and 4, interrupting virtualization. The model provided by the invention implements direct access of the distributed virtual machine monitor to equipment under a single system image, provides a complete I / O resource scheduling scheme, improves the utilization efficiency of I / O resources, and has good use value and broad development prospect.

Description

(1) Technical field

[0001] The present invention relates to the field of computer technology, in particular to the field of I / O virtualization in computer virtualization technology, and in particular to an I / O resource scheduling method of a distributed virtual machine monitor. Adopt the latest hardware virtualization technology, integrate the I / O resources distributed in multiple hosts, build a global virtual I / O space, schedule I / O resources for the upper guest operating system, and realize the distributed I / O resources of the guest operating system global management and use. (2) Background technology

[0002] Virtualization is a broad term generally used in computing to refer to computing and processing that runs on a virtual basis rather than a real one. Computer virtualization technology can abstract the physical resources of the computer and isolate hardware and software. Using virtualization technology, the cluster can be abstracted into a virtual machine with share...
