-description = """We use the `qemu-img map` command to retrieve metadata information from a qcow2 image. It functions as expected for non-encrypted qcow2 images. However, when the same command is executed on an encrypted qcow2 image, the output omits the `offset` key, which is critical for subsequent processing in our workflow."""
-reproduce = """1. Run qemu-img map on the encrypted incremental qcow2:
-Command:
-
-```
- qemu-img map --object secret,id=sec0,data=trilio --output json -U --image-opts driver=qcow2,file.filename=incremental.qcow2,encrypt.format=luks,encrypt.key-secret=sec0
-```
-**Observed Output:** The command executes but does not include the offset key in the JSON output.
-For example:
-```

-2. Decrypt the same encrypted incremental qcow2 image and re-run the qemu-img map command:
-**Decryption command:**
-```
-qemu-img convert -t writeback --object secret,id=sec0,data=trilio -O qcow2 --image-opts driver=qcow2,encrypt.key-secret=sec0,file.filename=incremental.qcow2 decrypt.qcow2
-```
-3. Run qemu-img map on the decrypted image:
-**Command:**
-```
-qemu-img map --output json -U decrypt.qcow2 
-```
-Here, we don't need to pass the encryption key as we have already decrypted the qcow2.
-
-**Observed Output:** The JSON output includes the offset key as expected. Example:
-```

-The missing `offset` key in the output of the `qemu-img map` command for encrypted qcow2 images disrupts downstream processes that rely on this metadata."""
