You'll need your sd card to be on an image format that supports snapshots (use 'qemu-img convert' to convert it to qcow2). Then you can use the monitor command 'savevm savename' to save a snapshot at any time. Reload an old snapshot with 'loadvm savename' or use the qemu command line '-loadvm savename' to start immediately from a snapshot. If the reloaded image hangs or otherwise behaves badly that's probably a sign that some device somewhere isn't restoring all its state; usually most easily determined by code inspection of all the devices that your machine instantiates. -- PMM
