Description

Upgrading treatment method and device

technical field

The present invention relates to the field of cloud computing, in particular to an upgrade processing method and device.

Background technique

In recent years, with the rapid development and gradual maturity of cloud computing technology, the resource utilization rate of physical servers has been improved, thereby reducing the operating costs of operators, and the network function virtualization (Network Function Virtualization, NFV for short) architecture has been widely used. Applications. Through NFV, the operating carrier of most telecom services has been transferred from the original physical server to the virtual machine. Through the decoupling of software and hardware and functional abstraction, the functions of network equipment are no longer dependent on dedicated hardware, and resources can be fully and flexibly shared to realize new technologies. Rapid business development and rapid deployment of applications, thereby reducing expensive equipment costs and operating costs.

However, in order to improve the performance of the virtual machine and keep the virtual machine running stably, thereby ensuring the stable operation of the business on the virtual machine, it is necessary to upgrade the (system) management program hypervisor from time to time. To upgrade the hypervisor, in most cases, the physical server needs to be restarted. If it is restarted directly, it will inevitably affect the business in the virtual machine running on the server, resulting in business interruption. For such situations, the traditional processing method is to pre-process the virtual machine on the server in a manual manner. There are two main methods: ① manually migrate the business on the virtual machine before the upgrade; ② migrate all the running virtual machines on the server to another server before the upgrade.

Using the first method, you may need to log in to each business virtual machine to migrate services or manually operate the virtualized network function manager (Virtualized Network Function Manager, referred to as VNFM) to migrate the virtual machine business it manages. More cumbersome. In the second way, since memory and storage factors need to be considered for migrating virtual machines, it may take a long time. In addition, during the migration process, packet loss may occur, which will cause business interruption. If there are many business virtual machines running on the server to be upgraded, the above two methods need to manually operate multiple virtual machines, which is cumbersome and may lead to misoperation, so it has certain limitations.

No effective solution has been proposed for the problem of defects in upgrading the physical server in the related art.

Taking the version server as an example below, the present invention will be further described in combination with specific embodiments.

The embodiment of the present invention automatically arranges the upgrade process, and controls the migration and recovery of services on the virtualized network function (Virtualized Network Function, referred to as VNF) through VNFM, which reduces manual participation and reduces the possibility of errors. Ensure that services are not interrupted during the upgrade process. Fig. 7 is a system architecture diagram according to the physical server automatic upgrade of the embodiment of the present invention, as shown in Fig. 7, version server includes a plurality of physical servers, promptly includes a plurality of mainframes, and VIM detects a certain physical server (also can be referred to as The hypervisor of the server) needs to be upgraded. First, the server is maintained, and then a message that the physical server will be upgraded is sent to each VNFM. After the VNFM receives the message, it migrates the virtual machine business it manages. After the business migration is completed, the VNFM notifies the VIM to allow the server to be upgraded. VIM shuts down the virtual machine running on the server, and then upgrades the hypervisor of the server. After the upgrade is completed, restores the maintenance status of the server, and then starts the previously closed virtual machine. After the virtual machine is turned on, VIM notifies the VNFM server to upgrade success. The virtual machine service managed by the VNFM is restored. After the restoration is completed, the VNFM notifies the VIM of the service restoration result, and the upgrade is completed.

Fig. 8 is a flowchart of an automatic upgrade of a physical server according to an embodiment of the present invention, as shown in Fig. 8, including the following steps:

Step S802, detect whether the physical server needs to be upgraded, if the detection result is yes, execute step S804, otherwise end; set the message notification address of each VNFM on the VIM; place the target version information to be upgraded on the version server. This step belongs to precondition setting. VIM detects that the hypervisor version of a server needs to be upgraded by comparing it with the version server.

Step S804, check the maintenance status of the physical server to be upgraded, and record the status, so that the status can be restored after the upgrade is completed.

In step S806, it is judged whether the physical server is in the maintenance state. If the current state is the maintenance mode, execute step S810; if the current state is the non-maintenance mode, execute step S808.

Step S808, to maintain the host, it is necessary to set the server to the maintenance mode.

Step S810, send a service migration message to the VNFM. The purpose of setting the server to maintenance mode is to prevent the server from still participating in virtualized resource scheduling during the upgrade process, so that other virtual machines may be started on the server, which is not conducive to the upgrade. processes and outcomes. The VIM will return the basic information of the server to be upgraded and the virtual machine running on it, and the VIM message to the notification address, and notify each VNFM in the form of a message, telling the VNFM that the server will be upgraded and the VNF business running on the server needs to be migrated.

In step S812, after receiving the message from the VIM, the VNFM migrates the VNF services it manages.

Step S814, shutting down the virtual machine.

Step S816, download the version file, upgrade the hypervisor, and after the service migration is completed, notify the VIM in the form of a message, informing the VNFM that the service managed by the VNFM has been migrated, and the hypervisor of the server can be upgraded; the VIM receives the information returned by each VNFM After the message is displayed, the currently running virtual machine on the server is shut down, and the list information of the shut down virtual machine is recorded. After all virtual machines are shut down, VIM downloads the target version to be upgraded from the version server according to the current hypervisor version number of the server, and executes the upgrade command after the version download is completed.

Step S818, restore the physical server to the non-maintenance mode; after the hypervisor upgrade command is successfully executed, restart the server (whether to restart needs to be determined according to the upgrade content and span of the target version); after the server is restarted, set the physical server to the non-maintenance mode , so that a powered-off virtual machine can be restarted on that server.

Step S820, restart the shut down virtual machine.

Step S822, restore the server to the saved state; start the recorded virtual machine that performs the shutdown operation. After all the virtual machines to be recorded are started successfully, judge the saved server status: if the saved status is in maintenance mode, perform maintenance operations on the server; if the saved status is in non-maintenance mode, do not perform any processing.

Step S824, sending a service recovery message to the VNFM; after the server status is restored, the VIM also notifies each VNFM in the form of a message, informing the VNFM that the host hypervisor has been upgraded successfully, and that the service migrated by the VNF needs to be restored.

Step S826, restore the VNF service; after the VNFM receives the notification message from the VIM, it resumes the VNF service; after the VNFM completes the restoration of the VNF service, it notifies the VIM that the VNF service managed by the VNFM has been restored by means of a message. After the VIM receives the return messages from all VNFMs, the upgrade ends.
