Currently we don't support so-called 'snapshots without (libvirt) metadata'. We do support though creation of the metadata in libvirt without actually invoking any qemu command. You can use virsh snapshot-create --redefine flag for it. The snapshot XML needs to have the same name as the qcow2 image's name. Note that some stuff might not work properly if you don't add a domain state XML which describes the hardware at the time the snapshot was taken. (A workaround would be to create a snapshot with the desired configuration with libvirt, then dump it and modify the name). Peter
