The server 104 may be configured as a virtualized platform/virtual machine, and the terminal 102 may be configured as a boot device, and the server 104 may be booted by the terminal 102, for example, when the server 104 generates a virtual machine, the server 104 may be booted by the boot device of the terminal 102, so that the server 104 installs an operating system or enters an already installed operating system. For another example, when the boot entry of the virtual machine is an optical disc, the boot device to be configured is an optical disc drive, when the boot entry of the virtual machine is a Universal Serial Bus (USB) interface, the boot device to be configured is a USB drive, when the boot entry of the virtual machine is a pre-boot eXecution Environment (PXE) resource, the boot device to be configured is a network card, and the server 104 may be implemented by an independent server or a server cluster including a plurality of servers.
In an embodiment, as shown in fig. 2, a configuration method for virtual machine boot is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:

s3: updating the selection sequence of the guide items in the default configuration according to the guide items matched with the virtual machine to be guided, and acquiring and storing guide configuration;
s4: booting the virtual machine to be booted through the boot configuration.
In a cloud computing service, a created or updated virtual machine needs to be booted to enable the virtual machine to install an operating system or run the operating system, in some application scenarios, different boot items need to be booted and started automatically, different boot items often need corresponding boot devices, as the number of virtual machines increases, the operation and maintenance pressure of the virtual machine for booting also increases, a default configuration can be provided for the virtual machine for booting, and according to the requirement of the virtual machine to be booted, a matched boot item is selected and updated to a boot configuration, so that the boot device is initialized, the boot requirements of the virtual machine are met, reasonable configurations of various boot items and boot devices of the virtual machine are realized, the boot configuration can be stored, and when the virtual machine fails or is lost, a boot policy can be provided for the virtual machine to be booted from the stored boot configuration, the method is suitable for scenes of mass production of the virtual machines in the industries such as education, scientific research and the like, can be used for configuring guide equipment in batches, greatly reduces the operation and maintenance cost of management and maintenance personnel, and can effectively reduce the operation and maintenance cost and pressure when the method is applied to large-scale or super-large-scale virtual machine groups.
In step S1, it is exemplarily illustrated that a default configuration of the virtual machine boot is obtained, where the boot items in the default configuration include but are not limited to optical discs, universal serial bus interfaces, USB drivers, and pre-boot execution environment resources, a certain number of boot items may be selected in the default configuration, for example, 3 to 5 boot items are not equal, and a maximum value and a minimum value of the number of boot items may also be selected in the default configuration, so as to provide multiple possibilities for booting the virtual machine, and also to be able to adapt to multiple scenarios during the virtual machine boot.
In step S2, it is exemplarily illustrated that, the default configuration is traversed, a boot entry matching the virtual machine to be booted is selected, so as to initialize the boot device of the virtual machine to be booted, for example, a priority order of the boot entries may be set in the default configuration and arranged according to a sequence number, the boot entry matching the virtual machine to be booted is selected by traversing the boot entry in the default configuration, and an available boot device is selected from the device list, so as to initialize the boot device, where the available boot device is a boot device that is marked to be accessible as a boot device or a virtual machine, so as to avoid the boot device in the device list from being in an occupied state and avoid a failure during booting the virtual machine.
In step S3, it is exemplarily illustrated that the boot entry matching the virtual machine to be booted may serve as a boot path of the current virtual machine to be booted, update the selection order of the boot entry in the default configuration, and pre-set the priority sequence number of the matching boot entry as the boot entry of the virtual machine to be booted, complete the update of the default configuration, acquire the boot configuration, and save the boot configuration.
In step S4, it is exemplarily illustrated that the virtual machine may be booted according to the boot configuration, so that the boot configuration boots the virtual machine to install or enter the operating system.
When a new virtual machine is generated in the application environment, the boot device that self-defines and selects each boot entry may be adapted through the default configuration, and may also select a matching boot entry by traversing the boot entries in the default configuration, as shown in fig. 3, the step S4 of booting the virtual machine to be booted through the boot configuration further includes:
s41: when the boot device of the virtual machine to be booted is changed, judging whether the boot device with the same type as the boot device before the change exists;
s42: if yes, selecting the guide equipment with the same type from the available equipment list of the guide item;
s43: and if not, traversing the rest guide items in the guide configuration, selecting the guide item matched with the virtual machine to be guided, and updating and storing the guide configuration.
In step S41, it is exemplarily illustrated that a boot device may be selected from the available device list of each boot item, when the boot device is changed, the boot device of the changed boot item is a designated boot device, marked as an available boot device, and it is determined whether there is another boot device of the same type as the changed boot device after the boot device is changed.
In step S42, it is exemplarily illustrated that the boot devices of the same type are selected from the available device list of the boot entry, for example, the available device list of each boot entry is an unmarked available device if the virtual machine allows the boot device types of each boot entry to be the same, and for example, the available device list of each boot entry is selected by traversing other boot entries if the virtual machine does not allow the boot device types of each boot entry to be the same.
When the boot device of the virtual machine is changed, the selected boot devices in the boot items may also be changed synchronously, and in step S43, for example, when the boot device is deleted, the boot item in which the deleted boot device is located is automatically selected as another boot item in the boot configuration, and when the boot device corresponding to the automatically selected current boot item is unavailable, the current boot item is deleted until the matched boot item is selected, and the selected matched boot item is saved in the boot configuration.
In some embodiments, the method further includes editing the existing virtual machine, and implementing operation and maintenance of the virtual machine, so that the current application scenario is adapted. Modifying a boot entry for a booted virtual machine when editing the booted virtual machine. For example, changing a current boot entry, traversing the boot configuration, and selecting a boot entry matching the booted virtual machine to initialize a boot device of the booted virtual machine; for another example, the current boot item is deleted, the rest boot items in the boot configuration are traversed, the boot item matched with the booted virtual machine is selected, wherein the rest boot items include the boot items except the current boot item in the boot configuration, meanwhile, the boot item information of the current boot item is also deleted, the boot device corresponding to the current boot item is deleted, the boot item matched with the booted virtual machine replaces the deleted current boot item, and the boot configuration is updated and saved.
In order to facilitate the priority ordering of each boot entry in the boot configuration, and to exclude exceptions and faults during the boot process of the boot entry, so as to facilitate the virtual machine to boot according to the boot configuration, in some embodiments, modifying the boot entry of the booted virtual machine further includes:
when the sequence numbers of the guide items in the guide configuration are discontinuous or repeated, the sequence numbers of the guide items in the guide configuration are arranged according to a lifting sequence, for example, the sequence numbers of the guide items in the guide configuration are arranged by adopting the lifting sequence, the efficiency and the correctness when the guide items are traversed are improved, the sequence number of the guide item with higher priority is selected, and for example, the sequence numbers of the guide items in the guide configuration are arranged by adopting the lowering sequence, so that the phenomenon that the sequence numbers of the guide items are discontinuous or repeated is avoided.
In order to facilitate continuous and stable operation of the virtual machine, debugging from a default configuration is avoided when the virtual machine is booted, the actual application scene requirements of the virtual machine boot can be met by storing the boot configuration, and in some embodiments, the boot configuration is stored when the virtual machine is shut down or started. For example, when the system is powered off, data in the boot configuration is persisted in a physical memory in a record form of a database or a file, and for example, when the system is powered on, the persisted data is read and written into a process parameter for starting the virtual machine, the process parameter is stored in a memory, when the virtual machine is started, the process parameter is read and transmitted to a boot program of a boot item in the virtual machine, and boot information is read and enters the boot program to complete the boot.
When disaster tolerance occurs in the server cluster, the virtual machine needs to be restored, and in the process of restoring the virtual machine, installation and import of an operating system are also needed, so that a certain configuration method for guiding the virtual machine needs to be adopted, and in order to avoid data loss caused by disaster tolerance of default configuration or guiding configuration, distributed storage or multiple backup storage can be performed on guiding configuration.

s55: if not, deleting unavailable guide items in the guide configuration;
s56: updating the boot configuration.
In step S51, it is exemplarily explained that the boot configuration is saved in a distributed manner to avoid a concurrent disaster tolerance, and for example, the boot configuration is saved in multiple copies, so that the virtual machine is protected in a backup manner, and all data of the boot device and the boot item are synchronously saved in the backup storage.
In step S52, an exemplary instruction that the virtual machine needs to be restored is obtained, and data is obtained from the boot configuration saved in the backup, so that the boot device and the boot entry complete booting the virtual machine.
In step S53, it is exemplarily explained that the boot configuration is traversed by the boot entry and the corresponding boot device, and whether the backup boot device exists is detected from the boot entry with sequence number 1, and whether the boot device is available is determined.
In step S54, it is exemplarily explained that when it is detected that the boot entry and the corresponding boot device are available, the available boot entry and the corresponding data information are retained.
In step S55, it is exemplarily explained that, when it is detected that the guidance item and the corresponding guidance device are not available, the unavailable guidance item and the corresponding data information are deleted until all guidance items are detected.
In step S56, the boot configuration is updated and saved, for example, information of the boot device matching the boot entry is saved in the boot configuration, and an association with the virtual machine is established.
