Integrating a Kickstart config file in an ESXi ISO fails to be found during installation (1026373)

  • When customizing an installation of an ESXi Installable ISO to include the kickstart configuration file, the installation fails at finding the ks.cfg file.
  • The same file ks.cfg can be located on a Web server, or NFS share, and will function correctly.
  • The ks.cfg files are located on the DVD-ROM (at the root directory or in a /ks directory) and the modified isolinux.cfg command may look as follows:

    append vmkboot.gz ks=cdrom:/ks/ks.cfg


This is due to an ESXi limitation of placing the file on a ISO 9660, UDF format for CD-ROM drives. Since ISO 9660, UDF format  supports only 8.3 UPPERCASE names. To work around this issue, change the command to reference the file in uppercase, for example
