Embodiment Construction

[0050] Such as Figure 4 As shown, the steps of the transparent event-driven dynamic discovery method of symbiotic virtual machines in this embodiment include:

[0051] 1) Initially establish an event linked list used to record pending events of the host and client and a symbiotic virtual machine list used to record the symbiotic virtual machine information of the physical machine node in the host and client;

[0052] 2) When the client joins the symbiotic virtual machine set, register with the host to monitor the registration action of the client, and monitor the / control / shutdown node corresponding to the client in the client to monitor the migration action of the client. Monitor the root directory node of the shared storage system XenStore corresponding to each client in the host computer to monitor the shutdown action of the client, and write the action corresponding event to the event chain of the host and client according to the monitoring result , And the host and client res...

Abstract

The invention discloses a transparent event-driven symbiotic virtual machine dynamic discovery method comprising steps of: initializing and establishing an event chain table and a symbiotic virtual machine list for recording the symbiotic virtual machine information of a physical machine node in a host machine and a guest machine; when the guest machine joins a symbiotic virtual machine set, registering in the client machine in order to monitor the registration operation of the guest machine, monitoring a control / shutdown node corresponding to the guest machine to monitor the migration operation of the guest machine, monitoring, in the host machine, a root directory node of an inter-domain sharing storage system corresponding to each guest machine in order to monitor the shutdown operation of the guest machine, writing corresponding events in the event chain table of the host machine and the guest machine, and enabling the host machine and the guest machine to process operation corresponding events in the local event chain table in order to update the symbiotic virtual machine list of the physical machine node. The transparent event-driven symbiotic virtual machine dynamic discovery method is transparent, low in cost, and high in efficiency for a virtual machine monitor and an operation system.

Description

Technical field [0001] The invention relates to cloud computing, operating system and network communication virtualization technology, in particular to a transparent event-driven dynamic discovery method for symbiotic virtual machines. Background technique [0002] Virtualization technology has become one of the important enabling technologies in the IaaS (Infrastructure as a Service) layer of the cloud computing environment. Virtual machine monitor (Virtual Machine Monitor, referred to as VMM) software to virtualize physical computer I / O devices, memory, processor and other hardware devices, virtualize multiple virtual machines on one physical computer (referred to as physical machine) Each virtual machine runs a guest system (Guest OS, guest operating system) and applications. The advantages of virtualization technology in terms of virtual machine function and performance isolation, online migration load balancing and system fault tolerance, application portability, improved r...
