As my first post I would like to link to a presentation about unattended ESX installations I gave at the Dutch VMUG Meeting ’07. The presentation can be downloaded over at the VMUG.

Although the presentation is a bit outdated since the release of ESX3.5, there still is a lot of common ground in the used method. Keep in mind that vimsh has been replaced by vmware-vim-cmd.

The used Ultimate Deployment Appliance hasn’t been updated for use with ESX3.5, so I’d recommend the ESX Deployment Appliance as a replacement.
