Hi Roberto,

Thanks for your information but....
When I'm writing about DC I mean defined DC in oVirt and so far I could 
see that when you define a storage domain in one oVirt DC it will not be 
available in another DC and I don't know what would happen if I would 
import it on the second DC.
In your setup, did you just define 1 DC and multiple clusters?
