[0054] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0055] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] See also Figure 1 , Figure 1 is a flow chart of a virtual machine data storage method provided by an embodiment of the present invention, such as Figure 1 As shown, the following steps are included:

[0058] Step 101: Create a virtual machine at a node whose storage capacity meets a preset requirement according to the acquired storage capacity of the node.

[0059] In this embodiment, the virtual layer includes a virtualized infrastructure management layer (VIM) and a virtual machine monitor (Hypervisor). The VIM is used to schedule nodes for creating virtual machines. To improve the scheduling capability of the VIM, the storage capacity of each node is obtained, and a suitable node is selected to create a virtual machine according to the storage capacity. The preset requirement may be, for example, that the storage capacity is greater than a preset value, which may be set as required.

[0060] Specifically, the selection methods include at least the following two:

[0061] First, the storage capacity values ​​of each node are sorted and compared, and the node with the largest storage capacity is used as the node for creating the virtual machine;

[0062] Second, a minimum threshold is pre-set, and when the storage capacity value is greater than the minimum threshold, the node is determined to be a node whose storage capacity meets the preset requirement;

[0063] According to the creation requirement, a node that meets the creation requirement is selected from nodes whose storage capacity meets the preset requirement as a node for creating a virtual machine. The creation requirement may be a special capacity requirement, such as selecting a node whose storage capacity is within a certain range or a certain value as a node for creating a virtual machine.

[0064] It should be noted that the storage capacity of a node refers to the storage capacity of a block device in the node, and the block device includes but is not limited to a disk.

[0065] Step 102: store the data generated by the virtual machine in corresponding block devices and partitions according to the newly added parameter information pre-set in the interface parameters, wherein the newly added parameter information includes partition information and information of block devices available for storage.

[0066] Hypervisor is software, firmware or hardware used to build and execute virtual machines. Add partition information and available storage block device information to the parameters of the POST / servers interface. According to the storage requirements of the virtual machine, select the appropriate block device in the block device category to store the data generated by the virtual machine. The number of block device categories is greater than 1, that is, the block device category is an enumeration of all available storage block devices, so that the virtual machine can have multiple block device mappings. When there is partition information in the interface parameters, the selected block device is automatically partitioned into different areas.

[0067] At the same time, you can add business parameters to the interface parameters. Business is the preset requirement of the virtual machine. The preset requirement can include whether the virtual machine can be migrated to other hosts. If it cannot be migrated, set this business parameter to avoid erroneous operation.

[0068] The virtual machine data storage method of the embodiment of the present invention creates a virtual machine at a node whose storage capacity meets preset requirements according to the different storage capacities of different nodes, so that the virtual machine has a larger or more suitable memory space for processing and storing data; by adding parameters for class enumeration for demarcating partitions and block devices in the parameters, the virtual machine can map multiple block devices and corresponding partition areas, increase the storage flexibility of the virtual machine data, and can store it in different block devices and different partitions according to different requirements. At the same time, business parameters are set to limit the preset requirements of the virtual machine, making the creation and use of the virtual machine more convenient.

[0069] See also Figure 2 , Figure 2 An embodiment of the present invention provides a method for storing virtual machine data.

[0070] Step 201: Create a virtual machine on a node with sufficient capacity.

[0071] The implementation method of this step can refer to the description in step 101, and will not be repeated here to avoid repetition.

[0072] Step 202: Select appropriate block devices and partitions according to the storage requirements of the virtual machine and the storage capacity of the block devices in the node to store the data generated by the virtual machine.

[0073] Take the following code as an example:

[0074] "block_device_mapping_v2":[{

[0075] "guest_format":"disk",

[0076] "uuid":"ac408821-c95a-448f-9292-73986c790911 (automatically obtain the image from VIM)",

[0077] "boot_index":"0",

[0078] "source_type":"image",

[0079] "volume_size":"25",

[0080] "destination_type":"local",

[0081] "delete_on_termination":true,

[0082] "tag":"disk1",

[0083] "disk_bus":"scsi"},

[0084] {

[0085] "guest_format":"disk",

[0086] "boot_index":"1",

[0087] "source_type":"blank",

[0088] "volume_size":"25",

[0089] "destination_type":"local",

[0090] "delete_on_termination":true,

[0091] "tag":"disk1",

[0092] "disk_bus":"scsi"}]

[0093] Add disk to the guest_format parameter under the server.block_device_mapping_v2 interface;

[0094] The code and parameters are valid when source_type is image (creating a volume from an image) or blank (creating a new volume) and destination_type is local.

[0095] boot_index=0 indicates the root disk of the virtual machine, and boot_index=1 indicates the data disk of the virtual machine.

[0096] Select a suitable disk according to the size of volume_size (25 in this embodiment) and the storage capacity of each block device.

[0097] In addition, the parameter partition is set in guest_format to represent the partition information. That is, when guest_format is partition, the block device is automatically partitioned and the appropriate partition is selected for the virtual machine.

[0098] At the same time, the server.is_static parameter can be added in the POST / servers interface to represent a new business parameter. Different values ​​of server.is_static are set to represent different business requirements. For example, server.is_static=1 means that the virtual machine can be migrated; server.is_static=0 means that the virtual machine cannot be migrated.

[0099] It should be noted that the guest_format parameter is used to indicate to the core network (MANO) how / whether to format the device before connection.

[0100] The disk enumeration value of guest_format (storable block device category) can be ext2 ext3 ext4 xfsswap;

[0101] The values ​​of source_type are: image, volume, snapshot, blank;

[0102] The values ​​of destination_type are: local and volume.

[0103] In this embodiment, the capacity of the computing server is obtained, and a node is selected based on the adequacy of the computing server capacity to install the virtual machine. When installing the virtual machine, the virtual machine is configured based on the enhanced POST / server guest_format and server.is_static parameters in this patent to determine whether the virtual machine can be migrated or evacuated, the number of block devices mapped to the virtual machine, and the local hard disk or partition, thereby completing the local deployment of the business virtual machine, that is, storing the data of the virtual machine locally according to the deployment situation.

[0115] Furthermore, if Figure 5 As shown, the configuration module 302 also includes:

[0119] If it exists, the partition is automatically created based on the partition information.
