If you taken the course and need to practice, check out the Sid Smith's site.   His site is called the daily hypervisor (http://dailyhypervisor.com).   With his assistance,  I was able to get this configured.   I used the following software packages:
VMware Workstation 6.5.2 for Linux, Windows XP, Windows 2003, VMware ESX 3.5 Update 3, VMware Virtual Center and Starwind's iSCSI Target Software.   It was easy after looking at his instructions and its quite cool.   Just remember, before you launch ESX Virtual Machines use the chmod linux command to grant enough permissions to make the virtual networks run correctly.   Everything else should be quite easy.   I will have more details in future postings.
