You can use this ISO installer image for regular boot or UEFI secure boot. However, the
vSphere Lifecycle Manager cannot verify the checksum of such an ISO image and you cannot
use it for upgrades by using vSphere Lifecycle Manager workflows.
Results
The ISO image includes your custom installation or upgrade script.
What to do next
Install ESXi from the ISO image.
Customizing Installations with vSphere ESXi Image Builder
You can use VMware vSphere
®
ESXi
Image Builder CLI to create ESXi installation images with a
customized set of updates, patches, and drivers.
You can use vSphere ESXi Image Builder with the vSphere Client or with PowerCLI to create an
ESXi installation image with a customized set of ESXi updates and patches. You can also include
third-party network or storage drivers that are released between vSphere releases.
You can deploy an ESXi image created with vSphere ESXi Image Builder in either of the following
ways:
n By burning it to an installation DVD.
n Through vCenter Server, using the Auto Deploy feature.
How the vSphere ESXi Image Builder Works
With vSphere ESXi Image Builder you can create ESXi image profiles for use by vSphere Auto
Deploy, add custom third-party drivers to existing image profiles and export to ISO or bundle, and
perform upgrades.
For basic concepts related to the way VMware vSphere software is created, packaged, and
distributed, see Software Packaging Units That vSphere Lifecycle Manager Can Consume in the
Managing Host and Cluster Lifecycle documentation.
