Virtual machine specification adjusting method and device

Abstract

The invention discloses a virtual machine specification adjusting method and device. The method comprises the following steps: indicating network function virtualization infrastructure to adjust the specification of a target virtual machine by adopting a first virtual machine specification adjusting instruction or a second virtual machine specification instruction, and migrating services in development of the target virtual machine to a cold-standby virtual machine or a hot-standby virtual machine before restarting the target virtual machine after the network function virtualization infrastructure completes the adjusting. The service data loss is avoided, the service interruption is avoided when the whole capacity adjusting is satisfied, the user cannot be offline, and the aim of adjustingthe virtual machine specification in the premise of not influencing the operation service of the virtual machine is realized.

Description

Technical field [0001] The invention relates to the field of network function virtualization, in particular to a method and device for adjusting the specifications of a virtual machine. Background technique [0002] Network virtualization technology has been favored by operators because it can save resources, reduce equipment costs and operation and maintenance costs, and is currently being applied in many places. When the previous office capacity cannot meet the current needs of user increase due to historical reasons of planning, the overall office capacity needs to be adjusted to expand the overall office capacity. At present, there are expansion and shrinkage mechanisms to meet this demand. [0003] However, although the aforementioned expansion and resizing mechanism can meet the needs of office capacity expansion, the virtual machine specifications are still limited to the original basis, which will cause the number of virtual machines to increase. Obviously, in the case of ...

But this method has a disadvantage that the virtual machine will automatically restart

This will cause the business carried out by the virtual machine to be out of control. If the specifications of the key virtual machine change, such as the main processor, this restart will cause all business data to be lost and affect the online user experience.
