Embodiment Construction

[0021] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0022] see figure 1 As shown, it is a schematic structural diagram of the Xen virtual machine architecture of the present invention. It can be seen from the figure that the Xen virtual machine architecture consists of an operating system, a virtual machine monitor, a BIOS system, and a hardware platform. in,

[0023] The function test program module is located in the user domain (operating system) layer and belongs to the user mode program, which is used for various tests on the hardware equipment.

[0024] The device front-end driver module is located in the user domain (operating system) layer and belongs to the kernel state program, which is used to communicate with the device back-end driver. Unlike traditional native device drivers, it cannot directly access hardware devices.

[0025] Xen Hypervisor: Located in the virtualization layer, it is us...

Abstract

The invention discloses a Xen virtual machine framework based on UEFI (unified extensible firmware interface) runtime service and an implementation method of the Xen virtual machine framework. The Xen virtual machine framework comprises a hardware platform, a BIOS (basic input / output system) system, a virtual machine monitor and an operating system, wherein the UEFI BIOS comprises a UEFI boot service and a UEFI runtime service; a privilege domain is communicated with a device front drive as one part of the UEFI runtime service in an operation stage of the operating system; the virtual machine monitor is located between the system hardware platform and the operating system software of the virtual computing domain to monitor lower hardware; the operating system comprises a device front drive in an inner nuclear layer and a functional test program in a user layer. Because the privilege domain is not stored in the hardware and is stored in a Flash chip as UEFI runtime service, the Xen virtual machine framework solves the problem that the existing Xen virtual machine framework has low-level safety protection. The simplification of the Xen privilege domain is achieved.

Description

technical field [0001] The invention relates to a new Xen virtual machine architecture, in particular to a new generation UEFI-based architecture and an implementation method thereof. Background technique [0002] The Xen virtual machine architecture is a de facto open source virtualization solution standard, which has the characteristics of open source, performance close to the original system, dynamic migration function that never stops, and support for the original operating system. "Unified Extensible Firmware Interface (UEFI)" is a new generation BIOS technical standard describing the interface between platform firmware and operating system and other application software. UEFI is mainly composed of a series of system tables containing platform-related information and startup services and runtime services for operating system boot programs and operating system calls. These components combine to provide a standard environment for the startup of an operating system and th...
