Before you can begin the process of deploying VMware Cloud Foundation you must prepare a minimum of four ESXi hosts that will form the management domain. To create a new VI workload domain, you must prepare a minimum of three ESXi hosts.

Preparing the ESXi hosts involves installing the correct version of ESXi and performing some basic configuration tasks. VMware Cloud Foundation supports two methods for preparing these ESXi hosts, either interactively or through the use of the VMware Imaging Appliance service (VIA) which is bundled within VMware Cloud Builder. For the supported ESXi version, see the Bill of Materials (BOM) section of the VMware Cloud Foundation Release Notes.
