ESXi 4.0 image type
The Add/Edit Image dialog box lets you define or edit the configuration settings of the ESXi 4.0 image file type.
The path to the folder containing the vmkboot.gz image file.
(Optional) Description of the image file
The kernel to be loaded when the device boots from the PXE server. Specify a path to the folder that contains the mboot.c32 file.
Command line arguments that the kernel requires at boot time. Separate arguments with a dash (---). Each argument should include the path to the folder containing the file (vmk.gz, sys.vgz, cim.vgz, oem.tgz, and license.tgz).
Because ESXi 4.0 can be used to provision only 64 bit devices, this option is checked and disabled.
Set as default image
The default image is the image that the system uses for auto-discovery. For example, when an unknown device PXE boots on your network, the system sends this device the default image.
You can also provision ESX and ESXi systems using Gentoo and Skip Linux boot images similar to Red Hat.
