Embodiment Construction

[0018] combine figure 1 , to illustrate the state-aware VM migration scheduling method based on the present invention, the steps are as follows:

[0019] Step 1: State Awareness, Combining figure 2 Describe the collection and storage process of node status.

[0020] Step 1: Collect node status. The state-aware monitoring system includes a management monitoring node CVMan, multiple cluster monitoring nodes CVClu and a CVMon daemon process deployed on each physical machine PM. CVMan is equivalent to the root node of the system. It is responsible for collecting the cluster information in CVClu, including the composition relationship of the system. By querying the cluster information, it can quickly obtain the mapping from VM to PM and from PM to cluster, and then obtain the access addresses of CVMon and CVClu. Users can get the corresponding monitoring information in CVMan through these addresses. CVClu is equivalent to the intermediate node of the system. It is responsible ...

Abstract

Provided in the invention is a state-sensing-based VM migration scheduling method. The method comprises: step one, state information of physical machines (PM) and virtual machines (VM) is collected in real time; step two, on the basis of a resource consumption sequence, VM sorting is carried out; step three, a destination and a migration path are determined for each to-be-migrated VM by using a simulated annealing algorithm; and step four, an exchange path is designed to realize maximum parallel migration.

Description

technical field [0001] The invention relates to a virtualization technology, in particular to a state-aware-based VM migration scheduling method. Background technique [0002] Cloud computing is the product of the combination of computer and network technologies such as Virtualization, Grid Computing, Distributed Computing, and Parallel Computing. Virtualization technology is the core technology supporting cloud computing. Virtualization has many benefits. It can realize the isolation of application environment, improve the utilization rate of computer resources, facilitate the integration of servers, and carry out reasonable resource allocation and load balancing. Server virtualization technology can make a physical server virtual into several servers. Load imbalance will reduce the system throughput rate, and even cause some services or VMs to be overloaded, making it impossible to provide services in time, affecting user experience. [0003] Using server virtualization...
