Yes that is correct - I would strongly advise against touching any of the 'hidden' volumes - those which don't show up in the Disk Utility application and definitely steer clear of any 'Container' volumes.SteveMacGeek wrote:@granada29 -- So -- to be clear -- in the following diskutil list, APFS Volume Prezdrive is my mounted boot volume.

I would also suggest (as in fact I did) that you make a copy of the .vdi file before making any changes. It is safe to delete the copy after you have succeeded with the "compact" and verified that the VM still boots.
