Abstract

The invention relates to a KVM (kernel-based virtual machine) virtualized service system and a data communication method for the same. The virtualized service system comprises a host operation system and more than one client operation system, wherein a KVM virtual machine runs on the host operation system and is provided with an inter-area communication module; each client operation system is provided with an area service module; and each area service module is provided with a data transmission buffer area which is shared by the inter-area communication module of the host operation system. When one of the client operation systems is provided with an equipment driving program, data of the area service module in the client operation system are interacted with data of the equipment driving program. Moreover, the inter-area communication module of the host operation system copies data among the data transmission buffer areas of the different client operation systems back and forth, so that data communication between the client operation systems is realized, the client operation systems can visit the equipment driving programs in the corresponding client operation systems, and equipment resources are shared.

Description

technical field [0001] The invention relates to a system virtualization technology, in particular to a KVM virtualization service system and a data communication method for improving the stability of a virtualization environment. Background technique [0002] Kernel-based Virtual Machine (KVM) is an open source server virtualization technology, which has been integrated into the kernels of various versions of Linux since Linux 2.6.20, and is widely used as a mainstream virtualization technology. The KVM virtual machine can use the scheduler and memory management functions of Linux without paying extra costs, automatically track and record the latest hardware device status and maintain the characteristics of scalability. With the resource management of the host operating system Linux itself and the support of CPU hardware virtualization technology, the KVM virtual machine can efficiently support multiple guest operating systems, enabling one computer to be used as multiple co...
