And many hypervisors will turn writing zeroes into an unmap/trim (qemu detect-zeroes=unmap), so running trim on the entire empty disk is often the same as writing zeroes. So +1 for encryption being the proper way here
+1 And to add to this: No, a newly created RBD image will never have 'left over' bits and bytes from a previous RBD image. I had to explain this multiple times to people which were used to old (i)SCSI setups where partitions could have leftover data from a previously created LUN. With RBD this won't happen. Wido
