[libvirt] F10: how to save snapshot back to image?

In Fedora 10 I've managed to get libvirt to call the emulator with
custom arguments so I can invoke -snapshot. I just replaced the
emulator in /usr/bin with my own script which adds the argument and then
calls the original emulator. This works fine. And the snapshot works
fine. I can make lots of changes and when I shutdown and restart then
all the changes are forgotten. Now after I'm satisfied with some
changes I want to save the snapshot back to the image file. I've tried
"Ctrl-Alt-s", but this does not work. I tried finding the QEMU console,
but Serial Console is grayed out in the menu. I don't know if that
would help anyway since this was a raw image and not qcow2 so I don't
think 'savevm' and 'loadvm' would work with raw.
Can someone tell me how to save these snapshots back to the image file?
