Problems solved by technology

Although this migration method can solve the overload problem of the physical machine that hosts the virtual machine, the migration of virtual machines across physical machines requires a huge amount of data to be synchronized and migrated, so it will inevitably cause a certain waste of resources

Embodiment Construction

[0016] refer to figure 1 Shown is a structure diagram of a virtual machine migration system 1 according to a preferred embodiment of the present invention. The virtual machine migration system 1 is mainly composed of a virtual machine migration control device 80, a shared I / O device 110 including multiple I / O (Input / Output, input / output port) units, and a physical machine cluster including multiple physical machines 100 compositions. The shared I / O device 110 is used as a shared input and output, and is respectively connected to each physical machine. The multiple physical machines are used to carry the virtual machine 70 ( figure 1 (not marked in ), the multiple I / O units are used as the transmission interface of the virtual machine 70 . The virtual machine migration control device 80 may be an external device attached to a physical machine or an I / O device, or may be a separate electronic device for controlling and managing the establishment, cancellation and migration of...

Abstract

A method for migration control of a virtual machine includes detecting usage of a first physical machine carrying a virtual machine and a first I / O unit which is used as a transport interface of the virtual machine; judging whether the first physical machine is in an overload state according to the usage of the first physical machine, and judging whether the first I / O unit is in an overload stateaccording to the usage of the first I / O unit; migrating the virtual machine from the first physical machine to a second physical machine when it is judged that the first physical machine is in an overload state; when it is determined that the first I / O unit is in an overload state, the transfer interface of the virtual machine is migrated from the first I / O unit to the second I / O unit. The invention also provides a virtual machine migration control device. The invention can flexibly and intelligently migrate the virtual machine and / or the transmission interface of the virtual machine, therebyreducing the waste of resources in the migration process of the virtual machine.

Description

technical field [0001] The invention relates to data processing technology, in particular to a virtual machine migration control method and device. Background technique [0002] Virtualization technology has been generally applied in computer systems, and the virtualization technology can virtualize the physical resources of a physical machine into multiple virtual machines, and the CPU (Central Processing Unit, central processing unit) of the physical machine is shared between each virtual machine. ), memory, storage, and network resources. In order to effectively utilize the physical resources on each physical machine and ensure the good operation of the virtual machine, a virtual machine migration method is currently used to achieve load balancing among the physical machines. For example, when a physical machine carrying a virtual machine fails or is overloaded, the virtual machine is migrated to a suitable physical machine. Although this migration method can solve the ...
