Abstract

The embodiment of the invention provides an inter-processor communication method and device, and virtualization equipment. The method is applied to the virtualization equipment. A first component is operated in the virtualization equipment, and a second component is constructed through virtualization on the first component. The method comprises the following steps that: the second component notifies the first component of the information of a plurality of virtual processors; the first component obtains the information of the plurality of virtual processors; and the first component sends an inter-processor interrupt signal to the plurality of virtual processors according to the information. The first component is notified of the information of the virtual processors in one time, so that communication frequencies between the first component and the second component are greatly reduced so as to greatly reduce the exiting frequency of the second component due to communication between the second component and the first component, the second component only exits for one time in a one-time multicast process, the time consumption of inter-processor communication is reduced, and the performance of the second component and the performance of the first component are improved.

Description

technical field [0001] The present application relates to the technical field of virtualization, and in particular to an inter-core communication method, an inter-core communication device and a virtualization device. Background technique [0002] In cloud computing IaaS (Infrastructure as a Service, infrastructure as a service), cloud operators provide hosted physical machines, virtual machines and other facilities for different users to use according to their actual needs. [0003] Virtual Machine (Virtual Machine) service is one of the core services of IaaS. It refers to a system virtual machine, that is, a complete computer system that can be simulated, has complete hardware system functions, and runs in a completely isolated environment. [0004] At present, a processor generally has multiple cores, and processors (cores) often communicate with processors (cores) through interrupts. ) is called Inter-Processor Interrupts (IPI), and the method of sending inter-core inte...
