Embodiment Construction

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

[0051] 1) Pre-initialize the establishment of an event chain list for recording pending events of the host and client in the host and client and a symbiotic virtual machine list for recording the symbiotic virtual machine information of the physical machine node;

[0052] 2) When the client joins the symbiotic virtual machine set, it registers with the host to monitor the registration action of the client, and monitors the / control / shutdown node corresponding to the client in the client to monitor the migration of the client. Monitor the root directory node of the inter-domain shared storage system XenStore corresponding to each client in the host to monitor the shutdown action of the client, and write events corresponding to the action into the event chain lists of the host and client according to the monitoring 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 technologies, 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 of the IaaS (Infrastructure as a Service) layer of the cloud computing environment. The I / O device, memory, processor and other hardware devices of the physical computer are virtualized through the virtual machine monitor (Virtual Machine Monitor, referred to as VMM) software, and multiple virtual machines ( Virtual Machine, referred to as VM), each virtual machine runs a guest system (GuestOS, guest operating system) and applications. The advantages of virtualization technology in virtual machine function and performance isolation, online migration load balancing and system fault tolerance, application portability, improved resourc...
