Open Stack

You might be able to change it via openstack command, probably something like 'openstack show image <Id>'  / 'openstack image set ?? <id>'

You can definitely download the image to a file and then upload a new image, specifying --min-disk. Something like 'openstack image save --file <file> <id>' and then just 'openstack image create --file <file> --min-disk <disk size in gb> <image name>'
