4 # Tests oVirt-like storage migration:
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
