Ticket #1918 (closed enhancement: fixed)
Support "differencing" disks, or don't delete immutable disk temp file on closedown
|Reported by:||sugarmonster||Owned by:|
I would like to create guests based on a "base" immutable disk image, plus changes. I know VBox already does this with immutable disks, but it then deletes the writes to a given session on closedown. I would like the option to persist these changes between sessions (preferably automatically so I don't have to check "save changes" every time).
The reason is speed and space: If I can create a base OS image and point guests at that, I have an "instant starting point" for a new guest without reinstalling the OS. If that guest then behaves like a normal PC from that point onwards I can install different apps etc without contamination. Plus it all happens for the disk cost of one base image + differences per guest.
