SQL cluster in private Hyper V network

Hi Not strictly a SQL question I know, but I am hoping someone doing the MCTS 70-432 has hit the same issue I have. In the MCTS training kit on clustering it details how to set up a test lab in virtual server to cluster windows servers with a shared SCSI bus for clustering. I am using Hyper V that does not support shared SCSI for clustering and I am therefore having to use MS iSCSI target software, which I have only just come across as a result of my issue. My question is am I going to have to install the iSCSI target software on a server inside the private virtual network I have create for clustering? or is there a way to present set up the target software on Hyper V host and present the VHD targets to the private guest servers. Pretty certain I have to set it all up in the private network and have even read that the degradation in performance is not what one would expect. If anyone has set up clustering for SQL in a private Hyper V network would love to hear how you went about setting it up. Many thanks Regards Rob
