# Tests oVirt-like storage migration:

#  - Create snapshot

#  - Create target image with (not yet existing) target backing chain

#    (i.e. just write the name of a soon-to-be-copied-over backing file into it)

#  - drive-mirror the snapshot to the target with mode=existing and sync=top

#  - In the meantime, copy the original source files to the destination via

#    conventional means (i.e. outside of qemu)

#  - Complete the drive-mirror job

#  - Delete all source images
