@Allan_Burton Welcome to Rockstor.
The issue you are having here is caused by there being no serial number on your sda device. Rockstor requires a unique serial on every device as is the case with real hw. Once you sort that out in your hyper visor / VM host your should be good.

We have a pending doc issue to add this to our Minimum system requirements section of the official docs:
