Problems solved by technology

[0016] In the process of realizing the present invention, the inventor found that the stop-and-copy stage in the existing virtual machine migration process will produce a short shutdown, which may affect the upper-layer application. When the high-availability mechanism of the application layer performs heartbeat monitoring , it may be considered that the virtual machine being migrated is abnormal, and disaster recovery is performed, causing conflicts

Embodiment Construction

[0059] The method for virtual machine migration provided by the present invention will be described below in combination with specific embodiments.

[0060] The present invention provides a method for virtual machine migration, the method comprising the following steps:

[0061] Step 101 , when the virtual resource management system VRMS determines that a virtual machine VM needs to be migrated, it obtains the address information of the VM and the application software running on the VM.

[0062] In practical applications, the migration of the virtual machine is generally determined by the administrator, and the VRMS determines whether the virtual machine is migrated according to the command issued by the administrator. This process is consistent with the prior art and will not be repeated here. And VRMS is a virtual resource management system, which stores the address information of all VMs, including the IP address information of the VM, the address information of the physica...

Abstract

The invention provides a virtual machine migration method, which comprises the following steps: when a VRMS (Virtual Resource Management System) determines that a VM (Virtual Machine) needs to be migrated, obtaining the address information of the VM and application software operating on the VM; sending a migration notification message to a management system of the application software; and notifying the management system of the application software to forbid o start a backup server by aiming at the VM according to address information, which is carried in the migration notification message, of the VM when the VM is migrated. Therefore, a phenomenon that a backup node is started by a management system corresponding to the application software operating on the VM when the VM is migrated can be avoided, and node conflict after migration is finished is avoided.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a virtual machine migration method, VRMS and system. Background technique [0002] In recent years, with the continuous rise of technologies such as cloud computing, data centers, and distributed environments, server virtualization technology has increasingly become a hot spot in the IT field. Server virtualization refers to the abstraction of server physical resources into logical resources, turning one server into several or even hundreds of virtual servers isolated from each other, and making hardware such as CPU, memory, disk, and I / O dynamically manageable "Resource pool", so as to improve resource utilization, simplify system management, realize server integration, and make IT more adaptable to business changes. Today, virtualization systems such as Xen and VMware have become relatively mature commercial virtualization products. [0003] virtual machine migration ...
