Deleting a VM with its data deleted only the images its disks pointed at. With external snapshots that is the newest overlay: the image the snapshots were taken on, the older overlays and the memory files stayed on disk, with nothing referring to them once the VM and its snapshot metadata were gone. The files the VM's snapshots were taken on, down each disk's backing chain, the overlays of snapshots kept off the chain after a revert, and the snapshots' memory files are now the VM's own too. A template the VM grew from ends the chain and stays, as does an overlay of a disk detached since. The backing references of the VM's own volumes no longer count as another domain's use, and a file another VM uses keeps the files below it. A backing file that cannot be read (other than one in no pool) stops the split before anything is deleted, instead of ending the chain there. |
