Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.

In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.

For the convenience of those skilled in the art to understand the technical solutions provided in the embodiments of the present application, a technical environment for implementing the technical solutions is described below.

A control method for a virtual machine, which is commonly used in the related art, mainly includes that, when a physical disk corresponding to a part of logical disks of the virtual machine fails, a user can only initiate virtual machine migration to migrate data of the virtual machine and other logical disks thereof to other physical machines, and a failed physical disk has a large influence on the virtual machine.

Based on the actual technical requirements similar to those described above, the control method for the virtual machine provided by the application can reduce the influence of the failed physical disk on the virtual machine by using a technical means.

The following describes a control method of a virtual machine provided in various embodiments of the present application in detail through an exemplary service scenario.

As shown in fig. 1, a virtual machine 12A and a virtual machine 12B are implemented on a physical machine 11, where the physical machine 11 is a host of the virtual machine 12A and the virtual machine 12B, and taking a cloud computing scene as an example, a virtual machine entity may be a cloud host. The physical machine 11 is provided with a physical disk P1 and a physical disk P2, where the physical disk refers to a physical hard disk, and P1 and P2 are two hard disks installed on the physical machine 11, and in actual use, the physical disk needs to be partitioned, and a new disk formed by partitioning is a logical disk. In fig. 1, physical disk P1 is partitioned to obtain logical disk L1 and logical disk L3, that is, logical disks L1 and L3 are mapped to physical disk P1; partitioning physical disk P2 results in logical disks L2, L4 and L5, i.e., logical disks L2, L4 and L5 map to physical disk P2. It should be noted that the number of virtual machines on the physical machine 11, the mapping relationship between the physical disk and the logical disk, and the correspondence relationship between the virtual machines and the logical disk in fig. 1 are only examples.

Also, for a while, as shown in FIG. 1, logical disks L1, L2, and L3 are mounted on virtual machine 12A, and logical disks L4 and L5 are mounted on virtual machine 12B. Assuming that physical disk P1 failed after that period of time, then, as shown in FIG. 2, during another period of time, logical disk L2 mounted on virtual machine 12A is controlled, without including logical disks L1 and L3 mapped to failed physical disk P1. Thus, it is achieved that the logical disk mounted on the virtual machine 12A is controlled not to include the target logical disk mapped to the failed physical disk, so that in the case of a physical disk failure, the virtual machine 12A may also run based on other logical disks besides the target logical disk, and compared with the case where the virtual machine 12A cannot run, or the virtual machine 12A needs to be migrated to other physical machines, the impact of the physical disk failure on the virtual machine is reduced.

Alternatively, in order to avoid the problem of disk identifier drift caused by the virtual machine 12A not having the target logical disk installed, as shown in fig. 3, a specific logical disk for occupying the target logical disk identifier may be installed, the disk identifier of the logical disk L1 may be occupied by the specific logical disk 1, and the disk identifier of the logical disk L2 may be occupied by the specific logical disk 2. Since the specific logical disk is used to occupy the drive letter of the target logical disk, is not a real logical disk capable of being used for data storage of the virtual machine 12A, but is equivalent to a dummy disk, the specific logical disk may be a read-only logical disk in order to avoid the virtual machine 12A writing data to the specific logical disk during operation. As shown in fig. 3, a specific logical disk may be created in the non-failed physical disk P2. Based on this, the specific logical disk 1 and the specific logical disk 2 of the virtual machine 12A may be mapped to the physical disk P2.

It should be noted that, the present application is mainly directed to a case where a part of logical disks of a virtual machine fails, and an operating system of the virtual machine is deployed in a non-failed logical disk.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Fig. 4 is a flowchart illustrating a control method of a virtual machine according to an embodiment of the present application, where an execution main body of the embodiment may be a control device of the virtual machine, and the control device may be included in the physical machine 11, or may also be included in another device, which is used for controlling the virtual machine on the physical machine 11, outside the physical machine 11. As shown in fig. 4, the method of this embodiment may include:

step 401, determining a physical disk fault of a target slot according to fault information, wherein a mapping relation exists between the physical disk and a target logical disk of a virtual machine;

step 402, controlling the logical disk mounted on the virtual machine to be another logical disk except the target logical disk, where the other logical disk and the physical disk except the physical disk of the target slot have a mapping relationship, and the other logical disk is used to support the running of the virtual machine.

In this embodiment, the control device may obtain the fault information from the hardware center, and the hardware center may monitor the state of the physical disk installed on the host in real time, and in the case of a fault of the physical disk of a target slot on the host, the hardware center may generate the fault information, where the fault information may include, for example, a slot number of the target slot. The hardware center may be a functional module implemented by software, and may be deployed on the host machine, or may be deployed on other devices besides the host machine, and when the number of host machines monitored by the hardware center is multiple, the fault information may further include an identifier of the host machine to which the target slot belongs, so as to indicate which slot of the host machine has a physical disk fault. The hardware center may actively send the fault information to the control device after the fault information, or the hardware center may return the fault information to the control device when the control device actively queries. Of course, in other embodiments, the control device may also obtain the fault information in other manners, which is not limited in this application.

After the control device obtains the failure information, it may determine that the physical disk of the target slot has a failure according to the failure information, where the physical disk and the target logical disk of the virtual machine have a mapping relationship, that is, the target logical disk is mapped to the physical disk. It is to be understood that the virtual machines are implemented in hosts corresponding to the target slots, the number of the virtual machines may be one or more, and the number of the target logical disks in one virtual machine may be one or more.

In this embodiment of the application, the control device may obtain information, such as a virtual machine and a disk, affected by the physical disk from a query. For example, according to the mapping relationship between the physical disk and the logical disk, a logical disk (i.e., a target logical disk) mapped to the physical disk may be determined to obtain a disk affected by the physical disk, and further, according to the mounting relationship between the logical disk and the virtual machine, a virtual machine mounted on the target logical disk may be determined to obtain a virtual machine affected by the physical disk. Of course, in other embodiments, the control device may also obtain information of the virtual machine, the disk, and the like affected by the physical disk in other manners.

In this embodiment of the present application, when it is determined that a physical disk of a target slot fails, and a logical disk having a mapping relationship with the physical disk is a target logical disk of the virtual machine, the logical disk mounted on the virtual machine may be controlled to be a logical disk other than the target logical disk, where the logical disk has a mapping relationship with the physical disk other than the physical disk of the target slot, and the logical disk is used to support the operation of the virtual machine. According to different stages of the virtual machine, specific ways of controlling the logical disk mounted on the virtual machine to be other logical disks than the target logical disk may be different.

Optionally, the controlling the logical disk mounted on the virtual machine to be another logical disk than the target logical disk specifically may include: and controlling the target logic disk to be unloaded from the virtual machine in the running process of the virtual machine. Based on the method, the logic disk mounted on the virtual machine can be controlled to be other logic disks under the condition of not stopping the virtual machine, so that the service provided by the virtual machine cannot be interrupted.

The control device may enable the target logical disk to be unloaded from the virtual machine by means of a virtualization service, and specifically, the control device may send an unloading message to the virtualization service, and the virtualization service may unload the target logical disk from the virtual machine according to the unloading message. The unloading of the target logical disk from the virtual machine may refer to removing the target logical disk from a Peripheral Component Interconnect (PCI) bus of the virtual machine. The virtualization service may be a software-implemented functional module, which may be deployed on a host, and may be used to be responsible for starting a Virtual Machine, unloading and mounting a disk, and the like, and specifically, the virtualization service may be a Kernel-based Virtual Machine (KVM) virtualization service. Of course, in other embodiments, the control of unloading the target logical disk from the virtual machine in the process of running the virtual machine may also be implemented in other ways, which is not limited in this application.

Optionally, the controlling the logical disk mounted on the virtual machine to be a logical disk other than the target logical disk may specifically include: and controlling the logic disk mounted on the virtual machine to be the other logic disks in the process of starting the virtual machine. The disk identifier of the logical disk to be mounted by the virtual machine can be controlled to only include the disk identifiers of other logical disks, but not include the disk identifier of the target logical disk, so as to control the logical disk mounted on the virtual machine to be other logical disks. The control device may mount the other logical disk to the virtual machine by using a virtualization service, and the mounting of the other logical disk to the virtual machine may be to add the other logical disk to a PCI bus of the virtual machine. Of course, in other embodiments, it may also be implemented in other manners that, in the process of starting the virtual machine, the logical disk mounted on the virtual machine is controlled to be the other logical disk, which is not limited in this application.

In this embodiment of the present application, optionally, in the case that it is determined that the physical disk of the target slot is failed, the physical disk of the target slot may be removed from the resource pool. The resource pool may be understood as a resource set that can be used for a virtual machine, and by removing the physical disk of the target slot from the resource pool, problems caused by resale of the physical disk of the target slot, for example, problems caused by newly creating a logical disk in the physical disk to newly create a failed logical disk, can be prevented. For example, the removal of the physical disk of the target slot from the resource pool may be achieved by setting an unavailable flag for the physical disk of the target slot in the resource pool. Of course, in other embodiments, the removal of the physical disk of the target slot from the resource pool may be implemented in other manners, which is not limited in this application.

In the embodiment of the application, the virtual machine may have a corresponding user, for example, in a cloud computing scenario, a cloud platform may provide different virtual machines for different users, so as to provide services for different users. Based on this, in order to ensure the control capability of the user on the virtual machine, before the logical disk mounted on the virtual machine is controlled to be a logical disk other than the target logical disk, the method may further include: a user of the virtual machine sends a fault message; and obtaining the isolation authorization of the user for the fault message feedback. For example, the control device may query for user information of the virtual machine to determine a user of the virtual machine. Of course, in other embodiments, the user of the virtual machine may be determined in other manners, which is not limited in this application.

For example, the failure message may carry an identifier of the virtual machine and an identifier of the target logical disk, so that the user may know which target logical disk or disks on which virtual machine failed. For example, after receiving the fault message, the terminal used by the user may display an interface as shown in fig. 5, and the user may select the "isolate" button or the "migrate" button in fig. 5, where selecting the "isolate" button may indicate that the user authorizes not to mount the fault logical disk, and based on this, the isolation authorization of the user for the fault message feedback may be obtained. Selecting a "migration" button may indicate that a user authorizes the migration of the virtual machine, based on which migration authorization of the user for the fault message feedback is obtained to migrate the virtual machine to a physical machine other than the physical machine. Of course, in other embodiments, the isolation authorization of the user for the fault message feedback may also be obtained in other manners, which is not limited in this application. It should be noted that the manner of prompting the user with the failure message in fig. 5 is only an example.

In this embodiment, as shown in fig. 3, to solve the problem of disk identifier drift, after the controlling the logical disk mounted on the virtual machine to be a logical disk other than the target logical disk, the method may further include: and controlling to create a read-only specific logical disk on a physical disk other than the physical disk of the target slot, and controlling to mount the specific logical disk to the virtual machine, wherein the specific logical disk is used for occupying a drive letter of the target logical disk. In one example, the control device may implement creating the read-only specific logical disk by using a storage service, and specifically, the control device may send a creation message to the storage service, and the storage service may create the read-only specific logical disk according to the creation message. The storage service may be a software-implemented functional module, which may be deployed on a host, and may be used to take charge of operations such as creation and deletion of a logical disk. Further, the control device may mount the specific logical disk to the virtual machine by means of a virtualization service, and specifically, the control device may send a mount message to the virtualization service, and the virtualization service may mount the specific logical disk to the virtual machine according to the mount message. Of course, in other embodiments, the creation and mounting of a specific logical disk may be controlled in other ways, which is not limited in this application.

In general, for some virtualization services, such as KVM-based virtualization services, the disk drive determines the drive letter of the logical disk based on the scanning order of the logical disk, and the virtual machine includes three logical disks, and the drive letters are/dev/vda,/dev/vdb and/dev/vdc, respectively, according to the scanning order of the three logical disks. Assuming that the logical disk with the disk identifier/dev/vdb is unloaded and the virtual machine is restarted, the disk identifier of the logical disk with the original disk identifier/dev/vdc is updated to/dev/vdb, and thus disk identifier drift occurs. Based on this, in order to avoid the disk identifier drift, after the logical disk with the disk identifier/dev/vdb is unloaded, the specific logical disk may be mounted to the virtual machine, when the specific logical disk is mounted, since/dev/vdb is unoccupied, the disk drive may determine that the disk identifier of the specific logical disk is/dev/vdb, and then the virtual machine is restarted, the logical disk corresponding to the disk identifier/dev/vdc will not change, thereby avoiding the problem of disk identifier drift.

In this embodiment of the present application, in a case that reading and writing of a disk need to pass through a storage service, the read-only characteristic of the specific logical disk may be implemented by the storage service. Currently, in other embodiments, the read-only characteristic of a specific logical disk may be implemented in other ways, which is not limited in this application. By using the specific logical disk as a read-only logical disk, the virtual machine can be prevented from writing data into the specific logical disk during the operation process, so as to support the effect that the specific logical disk is used for occupying the drive letter of the target logical disk. Further, to save resources, the controlling to create the read-only specific logical disk may specifically include: and controlling to create a specific logical disk with an initial space of 0 and read only on a physical disk other than the physical disk of the target slot.

In the embodiment of the present application, the control device may authorize a hardware center to maintain the physical disk of the target slot when determining that the physical disk of the target slot has a fault. In one example, the control device may send an authorization message to the hardware center, and the hardware center may initiate a repair procedure for the physical disk of the target slot based on the authorization message. Of course, in other embodiments, servicing of the physical disk of the target slot may be triggered in other ways. It should be noted that, the maintenance of the target slot physical disk may be to unplug the failed physical disk of the target slot and reinsert a new physical disk with the same specification as the failed physical disk; or, the position of the physical disk of the target slot may be to unplug the physical disk of the target slot, repair the physical disk, and reinsert the repaired physical disk into the target slot. It can be seen that the physical disk of the target slot before the maintenance and the physical disk of the target slot after the maintenance may be the same physical disk or different physical disks.

Further, after determining that the maintenance of the physical disk of the target slot is completed, the hardware center may return a maintenance success message to the control device, and the control device may determine that the failure of the physical disk of the target slot has been recovered according to the maintenance success message. Of course, in other embodiments, the control device may also know that the physical disk failure of the target slot is recovered in other manners, which is not limited in this application.

In this embodiment of the present application, when it is determined that the physical disk failure of the target slot has recovered, the method may further include the following steps: and controlling to rebuild the target logical disk on the physical disk of the target slot position and controlling to mount the rebuilt target logical disk to the virtual machine. The target logical disk is reconstructed on the physical disk of the target slot position, so that the consistency of the logical disks of the virtual machine before and after the failure recovery of the physical disk is ensured.

Similar to the aforementioned controlling of the logical disk mounted on the virtual machine to be another logical disk than the target logical disk, the controlling of reconstructing the target logical disk on the physical disk of the target slot and controlling of mounting the reconstructed target logical disk to the virtual machine body may include: and in the running process of the virtual machine, controlling to rebuild the target logical disk on the physical disk of the target slot position, and controlling to mount the rebuilt target logical disk to the virtual machine. Therefore, the reconstruction of the target logical disk on the physical disk of the target slot position can be controlled under the condition of not stopping the virtual machine, so that the interruption of the service provided by the virtual machine is avoided. Alternatively, the controlling to reconstruct the target logical disk on the physical disk of the target slot and to mount the reconstructed target logical disk to the virtual machine entity may include: and in the process of starting the virtual machine, controlling to rebuild the target logical disk on the physical disk of the target slot position, and controlling to mount the rebuilt target logical disk to the virtual machine.

Similar to the foregoing, the control apparatus may control, by means of a storage service, to reconstruct the target logical disk on the physical disk of the target slot, and control, by means of a virtualization service, to mount the reconstructed target logical disk to the virtual machine. Of course, in other embodiments, the target logical disk may be controlled to be rebuilt and mounted in other manners, which is not limited in this application.

In this embodiment of the present application, optionally, under the condition that it is determined that the physical disk failure of the target slot is recovered, the physical disk of the target slot may also be placed in a resource pool. The physical disk of the target slot position is placed into a resource pool, so that the physical disk of the target slot position can be sold again, for example, a logical disk can be newly built in the physical disk of the target slot position, and the utilization rate of resources is improved. For example, the physical disk of the target slot may be placed in the resource pool by clearing the unavailable identifier of the physical disk of the target slot in the resource pool. Of course, in other embodiments, the physical disk of the target slot may be placed in the resource pool in other manners, which is not limited in this application.

Similar to the foregoing isolation authorization, in this embodiment of the application, before the controlling mounts the target logical disk to the virtual machine again, the method may further include: sending a failure recovery message to a user of the virtual machine; and acquiring the recovery authorization of the user for the fault recovery message feedback. For example, the failure recovery message may carry an identifier of the virtual machine and an identifier of the target logical disk, so that the user may know which target logical disk or target logical disks on which virtual machine failed to recover. For example, the terminal used by the user may display an interface as shown in fig. 6 after receiving the failure recovery message, and the user may select an "ok" button or a "cancel" button in fig. 6, where selecting the "ok" button may indicate that the user authorizes failure recovery of the target logical disk, and based on this, the recovery authorization fed back by the user for the failure recovery message may be obtained. Selecting the "cancel" button may indicate that the user does not authorize the failover authorization of the target logical disk to migrate the virtual machine, based on which the recovery authorization fed back by the user for the failover message cannot be obtained, and thus the step of rebuilding and mounting the target logical disk is not performed. Of course, in other embodiments, the recovery authorization of the user for the fault recovery message feedback may also be obtained in other manners, which is not limited in this application.
