What Is Image Builder?
Image Builder is a set of command-line utilities that are used to
create and manage image profiles.
 An image profile is a group of VIBs that are used to create an ESXi
image.
Image Builder allows the administrator to build customized ESXi
boot images:
 Used for booting disk-based ESXi installations
 Used by VMware vSphere® Auto Deploy to boot an ESXi host in
memory
Image Builder is based on VMware vSphere® PowerCLI.
 The Image Builder cmdlets are included with the vSphere PowerCLI
tools.
