To Reproduce Steps to reproduce the behavior:

1. Deploy RHOSO 18.0 with Generic NFS Cinder backend
2. Create a volume 
3. Create an image from the volume using "openstack image create --volume <volume> <image>".
   This succeed
4. Create a snapshot from the volume using "openstack volume snapshot create --volume <volume> <snapshot>
5. Create an image from the volume using "openstack image create --volume <volume> <image>". But this time it fails with the following error

It seems that this issue occurs when we meet the following conditions

• Cinder backend is NFS (to be exact, remotefs)
• The volume format is qcow2
• The volume has snapshosts

Expected behavior

• Image creation succeeds

Bug impact

• Image cannot created from volume

Known workaround

• Use cinder backends other than NFS
• Delete snapshots of the volume

Additional context

• It seems that this issue occurs due to the change made in https://issues.redhat.com/browse/OSPRH-6735 and https://review.opendev.org/c/openstack/cinder/+/923247, that are fixes for CVE-2024-32498
