Guiding mirror image manufacturing method and device, electronic equipment and storage medium

Abstract

The invention provides a guided mirror image making method and device, electronic equipment and a storage medium, belongs to the technical field of computer networks, and solves the problems that if many cluster computing nodes exist, users are configured one by one, time is greatly wasted, virtual machine creation failure is caused easily due to missed configuration, If a user does not know whether a used operating system supports UEFI starting or not, mirror image manufacturing fails, repeated manufacturing exists, and a large amount of time of the user is wasted. The method comprises the steps of querying whether a computing node of a cloud platform has an OVMF installation file or not; selecting an operating system supporting UEFI startup; and respectively manufacturing a UEFI boot mirror image and a BIOS boot mirror image. According to the method, the double-boot mirror image is manufactured on the cloud platform of the OpenStack, whether the OVMF software is installed in the computing node of the server or not is checked in a one-key mode, whether the version of the operating system supports UEFI starting or not is intelligently verified, the system can be automatically switched to the needed boot mode to create the virtual machine, the mirror image manufacturing efficiency is improved, and a large amount of time is saved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method, device, electronic equipment and storage medium for making a boot image. Background technique [0002] Currently, the OpenStack-based cloud platform creates BIOS / UEFI-booted virtual machines. First, create a BIOS-booted or UEFI-booted image separately, and the UEFI-booted image has operating system restrictions. Not all systems support UEFI booting. , there is a risk of failure to make the image; then, upload the prepared BIOS boot or UEFI boot image to the OpenStack cloud platform, and after uploading the UEFI boot image, add the image metadata "hw_firmware_type=uefi" ; Finally, the user selects the required image to start the virtual machine.

[0002] Currently, the OpenStack-based cloud platform creates BIOS / UEFI-booted virtual machines. First, create a BIOS-booted or UEFI-booted image separately, and the UEFI-booted image has operating system restrictions. Not all systems support UEFI booting. , there is a risk of failure to make the image; then, upload the prepared BIOS boot or UEFI boot image to the OpenStack cloud platform, and after uploading the UEFI boot image, add the image metadata "hw_firmware_type=uefi" ;Finally, the user selects the required image to start the virtual machine

[0003] There are several problems with the above process. First, for UEFI-guided mirroring, OVMF software needs to be installed on the computing nodes on the server side and configuration items need to be added to the configuration file. If there are many computing nodes in the cluster, it is a great waste for users to configure one by one. It is also easy to fail to create a virtual machine due to lack of time; secondly, there is a limitation of operating system support in the production of UEFI boot image, if the user does not know whether the operating system used supports UEFI boot, this will cause the failure of image creation; thirdly, For the same operating system, if the user needs the image of BIOS boot and UEFI boot, the user needs to make it twice, which will waste a lot of time for the user
