Each will diverge. vmdk flat file

The flat file’s deepest layer speaks.

One day, the clone’s admin runs zerofree on the guest’s ext4 partition. Zeros overwrite unused blocks. But the zeros are data now. The ghost is exorcised — replaced by the void. But the void is still a story: “Someone cared enough to wipe me.” A flat file cannot snapshot itself. It needs a delta VMDK — a sparse child. But when a snapshot is taken, the flat file becomes read-only forever. Frozen in amber. All new writes go to -delta.vmdk . The flat file watches, unable to change, as
