[0001] The present application relates to the field of computer technology, and in particular to a method, device, electronic device and readable storage medium for deploying virtual machines on a virtualized cloud platform. Background Art

[0002] In the era of cloud computing, more and more businesses will be deployed on the cloud. Specifically, most businesses will choose to run their servers on the cloud in the form of virtual machines, which greatly facilitates business deployment and operation and maintenance.

[0003] It is understandable that the disks of virtual machines running on virtualized cloud platforms will inevitably fail. Since the virtual disks used by virtual machines in virtualized cloud platforms are all single copies, after the disk fails, the virtual machine cannot operate normally, which will not only cause data loss, but also affect the normal operation of the business on the virtual machine. Moreover, even if there are two copies, it is impossible to switch the business to another copy without shutting down the virtual machine when one copy has a problem, which will bring business interruption risks to the business deployment of the virtualization platform.

[0004] In view of this, how to reduce the probability of virtual machine business interruption and data loss running on the virtualized cloud platform and improve the stability and reliability of virtual machine business running on the virtualized cloud platform is a technical problem that technical personnel in the field need to solve.

[0012] Based on the capacity of the disk space, respectively divide the target disk space in each storage space of the target computing node;

[0013] Generate a mirrored logical disk consisting of target disk spaces with consistent data content and mutual data backup functions.

[0014] Optionally, the dividing the target disk space in each storage space of the target computing node based on the disk space capacity includes:

[0015] In each storage space of the target computing node, a target disk space having the same capacity as the disk space is created for the virtual machine.

[0016] Optionally, mapping the storage space from different storage devices to the computing nodes of the virtualized cloud platform includes:

[0017] Construct multiple node lists with different business fault tolerance capabilities; the computing nodes in each node list have the same business fault tolerance capabilities;

[0018] According to the physical parameters of each computing node of the virtual machine cloud platform, the number of running services and the stability requirements of running services, each computing node is divided into a corresponding node list;

[0019] Based on the total number of storage devices and the space capacity of each storage device, the storage space from different storage devices is preferentially mapped to the computing nodes in the node list with low service failure tolerance capability.

[0020] Optionally, before determining the disk space capacity of the virtual machine according to the configuration file of the virtual machine, the method further includes:

[0021] Automatically determine multiple candidate computing nodes that meet resource requirements for the virtual machine according to the configuration file;

[0022] A target computing node having storage space from different storage devices is selected from each candidate computing node to mount the virtual machine on the target computing node.

[0023] Optionally, before determining the disk space capacity of the virtual machine according to the configuration file of the virtual machine, the method further includes:

[0024] When receiving a virtual machine mount instruction, parsing the virtual machine mount instruction to obtain target virtual machine information;

[0025] Respond to the virtual machine mounting instruction to mount the virtual machine on the target computing node.

[0026] Another aspect of the present invention provides a device for deploying a virtual machine on a virtualized cloud platform, including:

[0027] A storage space mapping module is used to map storage spaces from different storage devices for computing nodes of a virtualized cloud platform in advance;

[0028] A virtual machine disk information acquisition module, used to determine the disk space capacity of the virtual machine according to the configuration file of the virtual machine; the virtual machine is mounted on the target computing node;

When the computer program is executed by a processor, the steps of the method for deploying a virtual machine on a virtualized cloud platform as described in any of the preceding items are implemented.

[0034] The advantage of the technical solution provided by the present application is that the computing nodes of the virtualized cloud platform share multiple groups of different shared storages, which come from different storage devices. The disk data is automatically written on each disk space of the mirrored logical disk, and the data of each disk space is consistent. In this way, after a disk fails, the remaining disks can replace the failed disk as a disk that can be used by the virtual machine. Since multiple disk spaces are composed of a mirrored logical disk, they appear as one inside the virtual machine, and the use of the virtual machine is the same as that of an ordinary virtual machine. In this way, when a disk space at the bottom of the virtual machine fails, since there is another disk that is running normally, the virtual machine is not aware of it. The failed virtual disk can be seamlessly switched to a normal virtual disk, and the virtual machine business and data will not be affected, which can effectively reduce the probability of interruption of the virtual machine business running on the virtualization platform and reduce the possibility of data loss of the virtual machine. At the same time, after the failed virtual disk is repaired, it can also be normally added to the redundant virtual disk group for data reconstruction to ensure the active-active state of the virtual disk of the virtual machine, thereby ensuring that the virtual machine business can run stably and reliably on the virtualized cloud platform.

[0035] In addition, the embodiments of the present invention also provide corresponding implementation devices, electronic devices and readable storage media for the method of deploying virtual machines on a virtualized cloud platform, further making the method more practical, and the devices, electronic devices and readable storage media have corresponding advantages.

[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] After introducing the technical solutions of the embodiments of the present invention, various non-limiting implementation methods of the present application are described in detail below.

[0045] See first Figure 1 , Figure 1 A flowchart of a method for deploying a virtual machine on a virtualized cloud platform provided in an embodiment of the present invention may include the following contents:

[0046] S101: Pre-map storage spaces from different storage devices for computing nodes of a virtualized cloud platform.

[0047] In this embodiment, each server runs on a virtualized cloud platform in the form of a virtual machine. Each server is a virtual machine. The virtualized cloud platform includes multiple computing nodes and management nodes, and each virtual machine is mounted on a computing node. Each computing node or certain designated computing nodes of the virtualized cloud platform of this embodiment share multiple groups of different shared storages, such as 2 groups of shared storages, and map these multiple storage spaces from different storage devices to all computing nodes in the virtualized cloud platform; the function of all computing nodes using the shared disk at the same time is realized through the cluster file system. These multiple groups of different shared storages can realize active-active disks, and each disk is placed on different storages. This ensures that the active-active virtual disks are placed on different shared storages, and there will be no simultaneous failure of these multiple active-active disks. The active-active in this step refers to a storage form with at least one redundant disk.

[0048] S102: Determine the disk space capacity of the virtual machine according to the configuration file of the virtual machine.

[0049] The management node of the virtualization cloud platform creates a disk active-active virtual machine and then sends it to the computing node of the virtualization cloud platform. That is, when the virtual machine is mounted on the computing node, the virtualization cloud platform sends the configuration file of the virtual machine to the corresponding computing node through its management node. The configuration file of the virtual machine can be an XML file of the detailed configuration of the virtual machine on the virtualization platform. The configuration file may include the size of the virtual disk. The computing node obtains the size of the virtual disk of the virtual machine mounted on it based on the received configuration file.

[0050] S103: Generate a mirrored logical disk for the virtual machine based on the disk space capacity and each storage space of the target computing node.

[0051] In this step, for the convenience of description, the computer node mounted by the virtual machine of S102 can be called the target computing node. The target computing node has been set up with multiple shared storage spaces in S101. In each storage space of the target computing node, a target disk space that can be used by the virtual machine can be created, and then these multiple target disk spaces are combined into a mirror logical disk. The data of the mirror logical disk is provided by multiple disks from different storage devices in S101, which means that the data will be written in multiple copies to provide redundancy, so that each disk space of the mirror logical disk can store the same data. These multiple disk spaces storing the same data are used as the disk space of the virtual machine together, so that the data of the virtual machine is written in each disk space of this mirror logical disk, so that the data will exist in multiple different storage spaces on the computing node. After one of the disks fails, it will not affect the data of the remaining storage spaces. The data of the remaining disks is still there, and the logical mirror disk can provide normal reading and writing. For the virtual machine, because the disk is active-active, the business is not affected in any way, ensuring that the business is not affected by disk failure at all times. When the faulty storage space is repaired, the raid technology can also be used to automatically reconstruct the data to keep the virtual machine's disk in an active-active state.

[0052] S104: Modify the disk space location of the configuration file to a mirrored logical disk, so that the mirrored logical disk provides disk space for the virtual machine.

[0053] After providing the virtual machine with a mirrored logical disk consisting of multiple disk spaces in the previous step, since this mirrored logical disk is to be used as the storage space of the virtual machine, it is necessary to change the disk path of the virtual machine on the target computing node by modifying the configuration file of the virtual machine on the target computing node, that is, to change the mirrored logical disk to the disk space location of the virtual machine, so that the virtual disk of the virtual machine becomes this mirrored logical disk. When data is written to this mirrored logical disk, the data of the virtual machine will be sent to each disk space of the mirrored logical disk. The data is written to the previous multiple storage spaces, thereby ensuring that if any disk has a problem, the virtual machine business will not be affected.

[0054] In the technical solution provided by the embodiment of the present invention, the computing nodes of the virtualized cloud platform share multiple groups of different shared storages, which come from different storage devices. The disk data is automatically written on each disk space of the mirrored logical disk, and the data of each disk space is consistent. In this way, after a disk fails, the remaining disks can replace the failed disk as a disk that can be used by the virtual machine. Since multiple disk spaces are composed of a mirrored logical disk, they are presented as one inside the virtual machine, and the use of the virtual machine is the same as that of an ordinary virtual machine. In this way, when a disk space at the bottom of the virtual machine fails, since there are other disks that are running normally, the virtual machine is not aware of it. The failed virtual disk can be seamlessly switched to a normal virtual disk, and the virtual machine business and data will not be affected, which can effectively reduce the probability of interruption of the virtual machine business running on the virtualization platform and reduce the possibility of data loss of the virtual machine. At the same time, after the failed virtual disk is repaired, it can also be normally added to the redundant virtual disk group for data reconstruction to ensure the active-active state of the virtual disk of the virtual machine, thereby ensuring that the virtual machine business can run stably and reliably on the virtualized cloud platform.

[0055] It should be noted that there is no strict order of execution between the steps in this application. As long as they comply with the logical order, these steps can be executed simultaneously or in a certain preset order. Figure 1 This is just a schematic and does not mean that this is the only execution order.

[0056] In the above embodiment, there is no limitation on how to execute step S103. In this embodiment, an optional method for generating a mirrored logical disk is provided, such as: Figure 2 As shown, the following steps may be included:

[0057] Based on the disk space capacity, the target disk space is divided in each storage space of the target computing node; in this embodiment, in order to facilitate management and take into account the total storage space of the computing node and the space occupied by the business execution of the virtual machine, a target disk space with the same disk space capacity can be created for the virtual machine in each storage space of the target computing node. That is, in this step, the soft raid technology can be used to take the same disk space as the virtual machine disk space on two different storages mounted on the computing node.

[0058] Generate a mirrored logical disk consisting of target disk spaces with consistent data content and data mutual backup function. In this step, disk mirroring technology such as RAID1 can be used to treat these multiple disks as a logical disk, and the data in the two disks remain consistent, so that data can be backed up mutually. If one disk fails, it will not affect the use of the logical disk.

[0059] This embodiment creates a disk space with the same size as the virtual machine disk, and uses soft raid technology to make a mirror logical disk for the two created disk spaces. The created logical mirror disk is changed to the active-active logical disk used by the virtual machine by modifying the virtual machine's xml file. In this way, when the data of the virtual machine is written, it is written on this active-active logical disk. In this way, the data will exist in two different storage spaces on the computing node. When the data in one storage space is lost, it will not affect the data in one storage space, and the active-active logical disk used by the virtual machine will not be affected.

[0060] It is understandable that there are multiple computing nodes in the virtualized cloud platform, and each computing node is allocated storage space of at least two different storage devices. However, the storage space of each storage device is limited, and it is very likely that the storage space of different storage devices cannot be allocated to each computing node of the current virtualized cloud platform. Based on this, the present application also provides another embodiment, which may include the following content:

[0061] Construct multiple node lists with different business fault tolerance capabilities; the computing nodes in each node list have the same business fault tolerance capabilities; divide each computing node into a corresponding node list based on the physical parameters of each computing node of the virtual machine cloud platform, the number of running businesses, and the requirements for the stability of running businesses; based on the total number of storage devices and the space capacity of each storage device, give priority to mapping storage space from different storage devices to the computing nodes in the node list with low business fault tolerance capabilities.

[0062] In this embodiment, the business fault tolerance capability refers to the requirements of the virtual machine business running on the computing node for business interruption. The higher the business fault tolerance capability, the lower the probability of the allowable interruption of the virtual machine business running on the computing node, and the data security impact is not high. The lower the business fault tolerance capability, the virtual machine business running on the computing node cannot be interrupted, and the data security requirement is high. Therefore, redundant disk space should be allocated to computing nodes with low business fault tolerance capability first, so that the virtual disks of the virtual machines running on them are in active-active state. The physical parameters of this step refer to the hardware and software environment and configuration of the computing node.

[0063] When storage resources are insufficient, this embodiment gives priority to allocating resources to computing nodes with low business fault tolerance capabilities, thereby improving the flexibility of deploying virtual machines on the virtualized cloud platform and ensuring the stability and security of the operation of virtual machines deployed on the virtualized cloud platform.

[0064] It can be understood that when a virtual machine is deployed on a virtual machine cloud platform, a suitable computing node will be matched for the virtual machine on the virtual machine cloud platform. This embodiment also provides multiple optional implementations of matching and mounting computing nodes for virtual machines, which may include:

[0065] As an optional implementation, multiple candidate computing nodes that meet resource requirements can be automatically determined for the virtual machine based on the configuration file; a target computing node with storage space from different storage devices is selected from each candidate computing node to mount the virtual machine on the target computing node. When matching the mounted computing node for the virtual machine, this embodiment gives priority to selecting a computing node with multiple shared storages as the target computing node, which can ensure the stable execution of the virtual machine business and the data security of the virtual machine cloud platform.

[0066] As another optional implementation method parallel to the above embodiment, when a virtual machine mount instruction is received, the virtual machine mount instruction is parsed to obtain target virtual machine information; the virtual machine mount instruction is responded to so as to mount the virtual machine on the target computing node. The virtual machine mount instruction of this embodiment is the computing node specified by the user for the mounting of the virtual machine, and the relevant information of the specified computing node is carried in the virtual machine mount instruction and sent to the management node. The management node obtains the target computing node information by parsing the instruction, and then sends the configuration file of the virtual machine to the target computing node so that the virtual machine is mounted on the target computing node.

[0067] This embodiment provides a variety of target computing node selection methods for virtual machines, improves the flexibility of virtualized cloud platforms in deploying virtual machines, and enhances user experience.

[0068] The embodiment of the present invention also provides a corresponding device for the method of deploying virtual machines on a virtualized cloud platform, which further makes the method more practical. Among them, the device can be described from the perspective of functional modules and hardware. The device for deploying virtual machines on a virtualized cloud platform provided by an embodiment of the present invention is introduced below. The device for deploying virtual machines on a virtualized cloud platform described below and the method for deploying virtual machines on a virtualized cloud platform described above can be referred to each other.

[0069] From the perspective of functional modules, see Figure 3 , Figure 3 A structural diagram of a device for deploying a virtual machine on a virtualized cloud platform provided in an embodiment of the present invention in a specific implementation manner, the device may include:

[0076] Optionally, in some other implementations of the present embodiment, the above-mentioned storage space mapping module 301 can be further used to: construct multiple node lists with different business fault tolerance capabilities; the business fault tolerance capability of the computing nodes in each node list is the same; according to the physical parameters of each computing node of the virtual machine cloud platform, the number of running businesses and the stability requirements of running businesses, each computing node is divided into a corresponding node list; based on the total number of storage devices and the space capacity of each storage device, the storage space from different storage devices is preferentially mapped to the computing nodes in the node list with low business fault tolerance capability.

[0077] Optionally, in some other implementations of the present embodiment, the above-mentioned device may also include a mounting node selection module, for example, for automatically determining multiple candidate computing nodes that meet the resource requirements for the virtual machine according to the configuration file; selecting a target computing node that has storage space from different storage devices from each candidate computing node, so as to mount the virtual machine on the target computing node.
