First of all thank you for your help, I've finally managed to get my Cluster configured properly but now that I create VMs I'm facing another problem. Whenever I start my VM I get this error. 

"VM TestVm is down. Exit message: Child quit during startup handshake: Input/output error."

I've googled around but haven't found any satisfactory solution. If anyone can help out it would be great. 

Regards
