and acquiring an initial uefi guide menu file from the mirror image file, and modifying the initial uefi guide menu file to acquire the uefi guide menu file.
It should be noted that since the uefi boot file does not exist in the image file, in order to ensure that the uefi system is normally started, the relevant file needs to be created through grub 2-efi-modules.
In a specific implementation, a hard disk storing a virtual machine system image file is firstly mounted to a PXE server, yum local sources are built in a PXE server, and then a "yum install-y grub 2-efi-modules" command installation grub2-efi-modules is run in the server. After successful installation, a uefi boot file is created by using grub2-mkstandalone command, named bootx64.efi, and copied to the/var/lib/tftpboot directory. Specifically, the instruction for creating the uefi bootstrap file in the server is as follows: grub2-mkstandalone-d/usr/lib/grub/x 86-64-efi/-O x 86-64-efi-modules ═ tftp net effect linux part _ gpt effect "-o bootx64. efi.
In the embodiment, a uefi boot file is created through grub2-efi-modules, so that the PXE server can boot and install the virtualization system in the to-be-installed server in the uefi mode.
