Hi, The target is for user to import .qcow2 image from download site and automatically stored as raw image. Read through [1], this seems doable. I am not sure the workflow. Does it download the whole qcow2 and convert it to raw locally, or download, convert and upload in a streaming way, which only require small space for caching? The question is that, how much local disk space is required for such import and conversion? [1] https://docs.openstack.org/glance/latest/admin/interoperable-image-import.html Thanks! Tony
