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? Thanks.
That's not supported at this time. The built in QCow2 snappshotting in QEMU is also rather dangerous with it known to corrupt data in a number of circumstances. We'd like to expose this functionality in libvirt eventually, but we've not made it a priority yet since its not really considered stable upstream either.
