Rocks Cluster rocks my socks. After battling with their FTP to grab the latest ISO, I was finally able to do a VMWare Install of version 4.2. The key for doing a VMWare install in workstation 5.5 was the following points:

• Create a VMWare Team
• Hard Drive sizes must be larger than 20 GiB
• Memory must be more than 640 MiB
• Remove the sound card and floppy
• In the vmware team assign all the machines to VLAN1
• The Frontend must have 2 NIC, assign them both to VLAN1 till the install is done at which point you can then bridge the public interface or host-only
• Boot PXE when the frontend is up for the clients and all will install

Let me state, Rocks is simply the best cluster software I have had the pleasure of using. Super High Five to the developers!
