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.
