Running
git grep '\$here' tests/qemu-iotests
has 0 hits, which means we are setting a variable that has
no use. It appears that commit e8f8624d removed the last
use. So execute the following cmd to remove all of
the 'here=...' lines as dead code.
sed -i '/^here=/d' $(git grep -l '^here=' tests/qemu-iotests)

# 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
