But as I have tro create many VMs with 120Gb of disk size of which probably only a part during time will be allocated, it would be unfeasible to make them all preallocated. I learned that thin is not good for block based storage domains and heavy I/O, but I would hope that it is not the same with file based storage domains... Thanks, Gianluca
