Multicore platform-orientated asymmetrical dispatcher for monitor of virtual machine and dispatching method thereof

Abstract

The invention discloses an asymmetrical dispatcher for a multicore platform-orientated asymmetrical dispatcher for a monitor of a virtual machine and a dispatching method thereof, which provides a specialized service core meeting the special high performance demand is provided for a client operation system based on the conventional virtual machine monitor VMM. The dispatcher comprises a service core request resolution module in a management domain, a Domain specific service core configuration module in VMM, a system top dispatcher module, a service dispatcher module, a shared memory mechanism module and a request inquiry module, and a hybrid virtual module in an HVM Domain. The asymmetrical dispatcher in the invention not only can provide different service cores according to the demands of upper layer Domain, but also can provide higher flexibility and expandability than the traditional dispatcher due to the consideration of the topological structure of a physical platform during the distribution of the service cores. In addition, the dispatcher provides an acceleration mechanism of a specific application type for the client operation system and improves the service efficiency of the entire platform.

Description

technical field [0001] The invention relates to a multi-core or many-core platform scheduling technology, in particular to a multi-core platform-oriented virtual machine monitor asymmetric scheduler and a scheduling method thereof, belonging to the technical field of computer operating systems and virtualization. Background technique [0002] System virtualization technology refers to the use of virtual machine monitor (Virtual Machine Monitor, referred to as VMM), the system software layer, to manage resources such as processor peripherals of the system platform, and to provide a virtual hardware execution environment for the guest operating system. These virtual hardware The execution environment becomes a virtual machine (Virtual Machine, VM for short). Each virtual machine (VM) includes virtual hardware resources such as processors, memory, and devices, and multiple VMs can run simultaneously on the same physical host. This technology originated in the 1960s. IBM first ...
