It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and claims of this application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may include other steps or elements not expressly listed.
Having described the technical solutions of the embodiments of the present invention, various non-limiting embodiments of the present application are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flow chart of an active maintenance method for a cloud platform physical host according to an embodiment of the present invention, where the embodiment of the present invention may include the following:
s101: when detecting that the physical host computer carries out software and/or hardware upgrading, automatically placing the physical host computer in a maintenance state, and simultaneously migrating the virtual machine running on the physical host computer.
It can be understood that, when the physical host performs software and hardware upgrading, for example, more memories and disks are added, devices such as a CPU/GPU/network card are replaced, an operating system is upgraded, virtualization software is updated, and maintenance operation needs to be performed, that is, the physical host needs to enter a host maintenance state. When the system detects that the physical host needs to be maintained, the physical host is automatically placed in a maintenance state, for example, the physical host can be characterized to be in the maintenance state by setting the maintenance state identification information. In the application, as long as the physical host is detected to be in the maintenance state, all the virtual machines running on the physical host are actively migrated.
The process of selecting a destination host for migration from a cluster for a virtual machine running on a physical host may include:
when a target migration host appointed instruction input by a user is received, migrating all virtual machines running on a physical host to the target migration host; when a target migration host appointed instruction input by a user is not received, judging whether an idle standby physical host exists or not; if the spare physical host exists, migrating all the virtual machines running on the physical host to the spare physical host; and if the idle standby physical host does not exist, migrating the virtual machine running on the physical host according to a preset scheduling rule.
That is, if the user designates the target host, the virtual machine on the node to be maintained is preferentially migrated to the designated target host; if the user does not specify the target host, and there are idle hosts in the cluster, i.e., the hosts are standby physical hosts, in order to ensure high availability of the cloud platform in extreme cases, the cloud platform plans some standby physical host nodes in some areas, and the nodes are normally in an idle state and do not run any cloud host. If an extreme condition occurs, such as a certain physical node in the area suddenly fails, the cloud host on the failed node can be timely recovered on the standby physical host, the customer service is not affected, and the virtual machine on the node to be maintained is migrated to the idle host; if the user does not designate a target host and there is no idle host in the cluster, the virtual machine on the node to be maintained is migrated out of the maintenance node according to a scheduling rule preset by the user or a scheduling rule for virtual machine migration in the related art, which is not limited in this application.
S102: and when the virtual machine is detected to finish the migration, the physical host is converted from the maintenance state to the non-maintenance state and the physical host is in the power-on state, automatically migrating the migrated virtual machine back to the physical host.
In this application, after the virtual machine is migrated in S101, a power-down operation may be performed according to whether a user selects to perform the power-down operation, and if the user inputs the power-down operation, the physical host performs the power-down operation. The physical host leaving the maintenance mode or entering the maintenance state can be executed according to the instruction of a user or an administrator, when the maintenance mode entering instruction input by the user or the administrator is received, the physical host enters the maintenance mode, and when the maintenance mode exiting instruction input by the user or the administrator is received, the physical host exits the maintenance mode. When the current state of the physical host is detected to be converted from the maintenance state to the non-maintenance state, that is, the physical host is maintained, the software and the hardware are upgraded, and the migrated virtual machines can be migrated back to the physical host. After the physical host completes maintenance and the physical host is in a power-off state, the physical host needs to be powered on to execute the virtual machine migration operation of S102. Wherein, the physical host can be represented to exit the maintenance state by clearing the maintenance conversion identification information of the physical host.
In the technical scheme provided by the embodiment of the invention, when the physical host needs to be maintained, the physical host is automatically placed in the maintenance state, and all the virtual machines on the maintenance node are migrated out. And determining whether to carry out power-on operation on the physical host according to the power state of the physical host, and when detecting that the physical host is powered on again and the physical host is converted into a non-maintenance state from a maintenance state, completely migrating the original virtual machines on the maintenance node back to the maintenance host. The method has the advantages that the active maintenance of the physical host is realized, the characteristics of the cloud management platform are enriched, the maintenance flow of the physical host is optimized, the maintenance operation of a cloud platform administrator on the physical host is greatly simplified, and the use experience of a user is improved.
The foregoing embodiment does not limit an implementation manner of performing virtual machine migration on a virtual machine on a physical host according to a preset scheduling rule, and the present application further provides an implementation manner, which may include:
acquiring all current hosts of the cloud platform except the physical host, and generating a target host list; removing the hosts meeting the filtering condition from the target host list by using a pre-configured filter to generate a candidate host list; and calculating the weight value of each candidate host in the candidate host list, and migrating the virtual machine running on the physical host to the candidate host with the minimum weight value.
The configuration conditions of the filters can be based on image attributes, available space, computing capacity, kernel utilization rate, disk utilization rate, number of running nodes and the like, a user can set a plurality of filters according to actual requirements and can also set one filter, the implementation of the application is not influenced, the filters are used for filtering the target hosts meeting the filtering conditions in the target host list, and the rest target hosts are placed in the candidate host list. When calculating each candidate host in the candidate host list, the weight value of each candidate host can be calculated based on a certain attribute such as the total number of running calculation nodes and the utilization rate of a disk according to actual needs, then the candidate hosts with the minimum weight values are ranked from small to large, and the candidate host with the minimum weight value is used as the host for virtual machine migration on the physical host.
As another optional implementation manner, in order to implement the maintenance operation of the physical host more flexibly, before S102, it may further include determining whether to send an instruction for executing the power-on operation of the physical host according to the power state of the physical host and whether the physical host exits from the maintenance state, after all the virtual machines on the maintenance node are migrated, it may be selected according to a user requirement whether to perform the power-off operation on the physical host, and it may be determined whether to perform the power-on operation on the physical host according to the power state of the physical host and whether to receive the instruction for exiting from the maintenance mode, and when the physical host is not in the maintenance state and the power-on operation is completed, the original mount virtual machine of the physical host may be automatically migrated back.
In addition, the present application further provides another embodiment, please refer to fig. 2, and fig. 2 is a schematic flow chart of an active maintenance method for a physical host of a cloud platform according to an embodiment of the present invention, where the embodiment of the present invention may include the following:
s201: and when detecting that the physical host computer is subjected to software and/or hardware upgrading, automatically placing the physical host computer in a maintenance state.
S202: and migrating the virtual machine running on the physical host, and generating a migration information recording file.
In order to facilitate management and query of maintenance information of the physical host and facilitate tracing of subsequent failures, during execution of migration of the virtual machine on the physical host, an action _ play, for example, may also be used to record the migration process, for example, the type, parameters, and results of each action may be recorded. The action _ play can be queried by the user through a specific interface. The migration information record file may include a migration type, a migration result, a migration time, ID information and name of the source host, ID information and name of each virtual machine, and ID information and name of the destination host. The migration type can be hot migration of active virtual machines and cold migration of inactive virtual machines, for example; the migration result is migration success or migration failure; in the process of migrating the virtual machine from the physical host, the source host is the physical host, and the destination host is the physical host to which the virtual machine is migrated. It can be understood that the virtual machines migrated from the same physical host may migrate to the same destination host, or migrate to different destination hosts, which does not affect the implementation of the present application.
S203: and judging whether a host power-off request instruction input by a user is received, if so, executing S204.
S204: and executing power-off operation on the physical host.
It can be understood that when the hardware of the physical host needs maintenance, the node needs to be powered off; accordingly, when the hardware maintenance is exited, the node needs to be powered up again. When the software of the physical host is maintained, the node is not necessarily powered off, so whether the physical host is powered off or not is the choice of the current user.
S205: and when the physical host is detected to be in a power-off state, actively sending an instruction for executing the power-on operation of the physical host.
S206: and when receiving a command of exiting the maintenance mode input by the user, automatically exiting the physical host from the maintenance state.
S207: and when the current state of the physical host is a power-on state, migrating the migrated virtual machine back to the physical host again to generate a back migration information recording file.
In order to facilitate management and query of maintenance information of the physical host and facilitate tracing of subsequent failures, during execution of the virtual machine migration process on the physical host, an action _ play, for example, may also be used to record the migration process, for example, may record the type, parameters, results, and the like of each action. The action _ play can be queried by the user through a specific interface. The migration information recording file includes a migration result, migration time, ID information and name of the source host, ID information and name of each virtual machine, and ID information and name of the destination host. The migration result can be migration success or migration failure; in the process of migrating the virtual machine back to the physical host, the source host is the physical host from which the virtual machine has migrated, and the destination host is the physical host in S01.
S208: when a physical host migration information query instruction input by a user is received, feeding back the migration information recording file and the return information recording file of the physical host every time to the user through a preset interface according to the migration time sequence.
In the application, when a user inputs a query instruction, the name of a physical host can be directly input, and all migration information recording files and return information recording files of the physical host are output; if the user inputs the query instruction including the name of the physical host and the migration time, outputting all migration information recording files and return information recording files of the physical host in the period of time; and if the file type is migration information or return information, outputting an information recording file corresponding to the physical host.
The steps or methods of the embodiments of the present invention that are the same as those of the embodiments of the present invention can refer to the descriptions of the same parts of the embodiments of the method described above, and are not described herein again.
In addition, it should be noted that, in the process of performing the maintenance mode, if any one of the above steps fails, the remaining steps are not executed, and the physical host fails to enter the maintenance mode; otherwise, the physical host successfully enters the maintenance mode. In the process of exiting the maintenance mode, if any step fails, the rest steps are not executed any more, and the physical host fails to exit the maintenance mode; otherwise, the physical host successfully exits the maintenance mode.
Therefore, the embodiment of the invention can realize the active maintenance of the physical host, automatically migrate the virtual machine running on the physical host, and automatically execute the migration operation after the maintenance of the host is finished, thereby simplifying the maintenance operation of the user and improving the use experience of the user.
