[nova] Snapshot Image Format

Hi, I am using nova 24.0. I have an image in raw format in glance store. I have created a volume backed instance from raw image. Then I have created the server image using nova api below with *createImage* . https://docs.openstack.org/api-ref/compute/?expanded=create-image-createimag...) OR via openstack server image create --name <name> <server uuid> The created image I see in glance store is in qcow2 format. I have set this option snapshot_image_format in nova.conf but still it creates the images in qcow2 format. How config need to be done if i need to save server image in raw format ? Ammad
