Title:
[Feature request] loadvm snapshot as read-only
Status in QEMU:
Expired
Bug description:
There are many ways to take and manage snapshots in QEMU, but one main
feature that's missing is the ability to 'loadvm' a LIVE snapshot and
have all future changes redirected to a temporary file. This would
effectively be combining the -loadvm and -snapshot switches and make
the snapshot read-only. With this feature, users would be provided a
"sandbox" and be able to start and restart the same live snapshot
without corrupting the image in doing so.
I found a lot of discussion about this topic on the mailing list years
ago, including some patch submissions, but none of the conversations
panned out.

What would it take for this feature to be added, and can we use the
patches submitted by Eddie Kohler to enable this feature?
