Problems solved by technology

[0025] However, when the virtualization technology is applied to the resource pool of the base station, due to the high real-time characteristics of mobile communication, the processing time of the virtual machine for the baseband signal is required to be within a few milliseconds, so when the virtual machine is migrated online, the memory page of the virtual machine changes quickly It may be faster than the speed of memory copying during the migration process, resulting in the failure of the memory copying process of the virtual machine during the migration process to converge, resulting in the inability to complete the online migration process normally

Embodiment Construction

[0073] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0074] It can be seen from the background art that the reason for the failure of online migration of virtual servers is that the memory of the virtual machine changes faster than the memory copying during the migration process, so that the memory copying process between the virtual machines before and after the migration cannot converge. In order to overcome this problem, the present invention first selects the switching target carrier when performing the online migration of the virtual machine on the source physical server, switches the users of the carrier to be migrated running on the virtual machine to the switching target carrier, and then switches the idle virtual machine to the switching target carrier. machine to the target physical serve...

Abstract

The invention discloses an online migration method, an online migration system and a device of a virtual machine. The target carrier wave is selected and switched during online migration of the virtual machine on a source physical server, the user of the virtual machine is transferred to the switched target carrier wave, and the idle virtual machine is transferred to the target physical server. The user in the internal storage is already transferred to the other carrier waves before the virtual machine is migrated on line, so that the internal storage of the virtual machine will not change during the online migration process, the situation that the reproduction process of the internal storage of the virtual machine is unable to restrain can be avoided and the online migration of the virtual machine can be successfully achieved.

Description

technical field [0001] The present invention relates to the field of mobile communication wireless access, in particular to a virtual machine online migration method, system and device. Background technique [0002] With the development of mobile communication wireless access networks, wireless access devices are undergoing an evolution process from traditional integrated base stations to distributed base stations and then to base station resource pools. [0003] The traditional integrated base station equipment includes two main functional units, namely the radio frequency unit and the baseband processing unit (BBU, Baseband Unit), which respectively perform related processing of wireless signals and baseband signals. Specifically, the baseband signal is carried on a carrier in a certain range, and the processing of the baseband signal is the processing of the carrier. The two functional units are located in the same cabinet hardware equipment, resulting in a large base st...
