Deploying ESXi through Foreman


At the time of writing this (Foreman v1.18), ESXi deployment through Foreman is not supported natively. The problem is exacerbated by the fact that the ESXi Legacy BIOS bootloader depends on an older Syslinux (v3.86) and GRUB2 not being able to chainload the ESXi EFI bootloader. However there are quite a few articles on the Internet that have attempted to work around these issues. This post is an attempt to bring all the information together in one place, simplify the process and most importantly, support both Legacy BIOS and UEFI modes of installation. Huge thanks to the foreman developers for helping me out whenever I was stuck.
