Prepare or Unprepare a Provider vDC Host
When you add an ESX/ESXi host to a vSphere cluster that vCloud Director uses, you must prepare the host
before a provider vDC can use its resources. You can unprepare a host to remove it from the vCloud Director
environment.
For information about moving running virtual machines from one host to another, see “Move Virtual Machines
from one ESX/ESXi Host to Another,” on page 101.

host.
