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] see figure 1 As shown, it is a structural 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 a plurality of I / O (Input / Output, input / output ports) units, and a physical machine cluster including a plurality of 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 plurality of physical machines are used to host virtual machines 70 ( figure 1 (not indicated in ) is running, 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 an electronic device that exists independently, and is used to control and manage t...

Abstract

A virtual machine migration control method, comprising: detecting the usage of a first physical machine bearing a virtual machine and a first I / O unit serving as a transmission interface of the virtual machine; according to the usage of the first physical machine Determine whether the first physical machine is in an overloaded state, and determine whether the first I / O unit is in an overloaded state according to the usage of the first I / O unit; when it is determined that the first physical machine is in an overloaded state When it is in an overloaded state, migrate the virtual machine from the first physical machine to the second physical machine; when it is determined that the first I / O unit is in an overloaded state, transfer the transmission interface of the virtual machine Migration from the first I / O unit to the second I / O unit. The invention also provides a virtual machine migration control device. The present invention can flexibly and intelligently migrate the virtual machine and / or the transmission interface of the virtual machine, thereby reducing the waste of resources in the virtual machine migration process.

Description

technical field [0001] The present invention relates to data processing technology, in particular to a virtual machine migration control method and device. Background technique [0002] Virtualization technology has been widely used in computer systems. The virtualization technology can virtualize the physical resources of a physical machine into multiple virtual machines, and each virtual machine shares the CPU (Central Processing Unit, central processing unit) of the physical machine. ), memory, storage, and network physical 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 balance of each physical machine. For example, when the physical machine hosting the virtual machine fails or is overloaded, the virtual machine is migrated to an appropriate physical machine. Although this migration method can solve the ov...
