[Qemu-devel] [Bug 726619] [NEW] loadvm does not load (offline) snapshot anymore

[Ralf Haferkamp]

Public bug reported:

qemu Version: 0.14.0
The problem is present in the current code from git master as well.

Loading a snapshot that was created while qemu was not running (using
qemu-img) does not seem to work anymore.

Using "loadvm <snapshot-id>" in the qemu monitor does not have the
desired effect. Not even an error message is displayed.

I was able to track down the problem (using git bisect) to this commit:
http://git.qemu.org/qemu.git/commit/?id=f0aa7a8b2d518c54430e4382309281b93e51981a

After reverting that commit in my local git checkout everything is
workin as expected again.

Is there even a use case for this? While an OS is running, just silently
replacing the disk contents isn't going to work. And if you're rebooting
anyway, you can as well load the snapshot offline.

In fact, that commit only lets loadvm fail earlier. Before, loadvm would
have loaded all disk snapshots and then returned -EINVAL because there
was no VM state, now it fails immediately (the VM is stopped in both
cases because of the failure).

I think the correct fix is to add an error message.

Triaging old bug tickets ... can you somehow still reproduce this
problem with the latest version of QEMU (currently v2.9), or could we
close this ticket nowadays?
