Scheduling method for virtual machine migration and system

Abstract

The invention provides a scheduling method for virtual machine migration. The scheduling method includes the flowing steps that S1, a cross-domain migration request of a virtual machine is obtained; S2, whether the virtual machine can be migrated out or not is judged according to safety information of the virtual machine and the domain safety strategy of a source safety domain where the virtual machine is located; S3, if yes, the safety information of the virtual machine is parsed, and the target safety domain to which the virtual machine can be migrated is determined according to the central safety strategy; S4, the cross-domain migration request of the virtual machine is transferred to the target safety domain; S5, whether the target safety domain allows the virtual machine to be migrated to the target safety domain or not is judged according to the safety information of the virtual machine and the domain safety strategy of the target safety domain; S6, if yes, the target safety domain receives the cross-domain migration request of the virtual machine, and the virtual machine is migrated to the target safety domain from the source safety domain. By means of the scheduling method and system for virtual machine migration, potential safety hazards caused by migration of the virtual machine can be avoided, optimizing operation of system overall performance and load balance are guaranteed, and service safety and performance of the system are taken into consideration as well.

Description

technical field [0001] The invention relates to the technical field of computer information security, in particular to a virtual machine migration-oriented scheduling method and a system thereof, and is particularly suitable for cloud computing virtual machine migration. Background technique [0002] Cloud computing is an Internet-oriented distributed computing service, which can obtain the required resources (such as network, server, storage, application and service, etc.) Resources can be provisioned and released quickly with minimal administrative cost or service provider intervention. [0003] The dynamic migration of virtual machines is one of the characteristics of cloud computing. Usually, the scheduling strategy of virtual machine migration in cloud computing environments is based on the method of real-time monitoring of physical host performance to achieve load balancing. This aspect often brings a lot of computing consumption. , and cannot effectively solve the pr...

Problems solved by technology

For example, computing resources such as CPU occupancy rate and memory usage rate are used as reference conditions for migration. Therefore, as the number of computing nodes increases, the load of the migration scheduler will increase exponentially. At this time, the performance requirements for the migration scheduler It will also be very high, prone to performance bottlenecks

[0005] 2. When the migration scheduler schedules virtual machines to hosts or host computing nodes, it does not consider the security level differences and mutual exclusion between computing nodes, which will bring security risks and easily lead to virtual machine failures. The security level is lowered, which poses a security threat to user data in the virtual machine and brings hidden dangers in security performance
