Has anyone tried Open-e Lite SAN running as a VM? What is the recommended VM configuration? How much CPU and RAM should be the optimized performance?

After installing it to a 256GB vmdk, it was not able to see any available unit to use with this message: No system volume found. Do I have to manually set a new partition for it to see an unit?

btw, we decided to give up on SANmelody because it often freeze up iSCSI traffic without any reason once every few weeks.
