| 5 | # - Create snapshot |
| 6 | # - Create target image with (not yet existing) target backing chain |
| 7 | # (i.e. just write the name of a soon-to-be-copied-over backing file into it) |
| 8 | # - drive-mirror the snapshot to the target with mode=existing and sync=top |
| 9 | # - In the meantime, copy the original source files to the destination via |
| 10 | # conventional means (i.e. outside of qemu) |
| 11 | # - Complete the drive-mirror job |
| 12 | # - Delete all source images |
