The QEMU project is currently considering to move its bug tracking to another
system. For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state
back to "New" within the next 60 days, otherwise this report will be marked as
"Expired". Or mark it as "Fix Released" if the problem has been solved with a
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
[Feature request] loadvm snapshot as read-only
Status in QEMU:
Incomplete
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?
