One of the reasons I setup an NFS share is so that I can have an inexpensive shared storage place for my VMs on the ESX Server 4.0. I can also use the features on vCenter like VMotion and Fault Tolerance using the shared storage. Creating the NFS is only available for the Windows 2003 R2 SP2. For ESX Server’s vCenter, you will also need to install the 32-bit version of the OS. I have a desktop client which I have installed the OS and also where I will store the VMs at. I also have vCenter & vSphere Client installed on the system as well.
