So I create a snapshot of VM1 and then "Clone". Inside the "Resource Allocation" section, the drop-down for the 3 disks seems not enabled, in the sense that for every disk it contains only the name of the origin SD, so for 2 disks it contains SDA and no other SD to be chosen, for 1 disk it contains SDB and no other SD to be chosen.See here:Can anyone replicate this in 4.1.5 to see if it is a problem of mine?
