Embodiment Construction

[0113] As shown in Figure 1, a virtual machine system based on processor virtualization technology includes a processor with virtualization technology, other underlying hardware except the processor, and a virtual machine monitor running in the virtual machine extended root operating mode 1. Several virtual operating systems running in the non-virtual machine extended root operation mode. One end of the virtual machine monitor is connected to each virtual operating system through its virtual hardware platform interface, and the other end is connected to other underlying hardware devices except the processor. Each virtual operation The system is directly connected to the processor.

[0114] The virtual machine monitor includes a device virtual module, a memory virtual module, a virtual hardware platform interface, an interrupt descriptor table, a virtual machine control structure, and a global descriptor table. The virtual machine control structure is used to control the memory ...

Abstract

A virtualizer system based on processor virtualization technology consists of processor with virtualization technique, bottom layer hardware, virtualizer monitor and a numbers of virtual operation system. It is featured as switching in one end of virtualizer monitor to various virtual operation systems through virtual hardware platform interface and another end to said bottom layer hardware device except processor and connecting various operation systems directly to processor.

Description

technical field [0001] The invention relates to a virtual machine system, in particular to a virtual machine system based on processor virtualization technology and its software and hardware environment configuration and module realization. Background technique [0002] Virtualization technology refers to the operation of computing elements on a virtual rather than a real basis. Virtualization technology can expand the capacity of hardware and simplify the process of reconfiguring software. Processor virtualization technology can simulate multiple processors in parallel with a single processor, allowing one platform to run multiple operating systems at the same time, and applications can run in independent spaces without affecting each other, thereby significantly improving computer work efficiency. [0003] Virtualization technology is a huge technological advancement, specifically in terms of reducing the overhead associated with software virtual machines and supporting a...
