Details below : *My backing chain per qemu-img :* [stack@devstack-f21 test]$ qemu-img info --backing-chain snap4.qcow2 image: snap4.qcow2 file format: qcow2 virtual size: 1.0G (1073741824 bytes) disk size: 196K cluster_size: 65536 backing file: ./snap3.qcow2 Format specific information: compat: 1.1 lazy refcounts: false image: ./snap3.qcow2 file format: qcow2 virtual size: 1.0G (1073741824 bytes) disk size: 196K cluster_size: 65536 backing file: ./snap2.qcow2 (actual path: ././snap2.qcow2) Format specific information: compat: 1.1 lazy refcounts: false image: ././snap2.qcow2 file format: qcow2 virtual size: 1.0G (1073741824 bytes) disk size: 196K cluster_size: 65536 backing file: ./snap1.qcow2 (actual path: ./././snap1.qcow2) Format specific information: compat: 1.1 lazy refcounts: false image: ./././snap1.qcow2 file format: qcow2 virtual size: 1.0G (1073741824 bytes) disk size: 196K cluster_size: 65536 backing file: ./base.qcow2 (actual path: ././././base.qcow2) Format specific information: compat: 1.1 lazy refcounts: false image: ././././base.qcow2 file format: qcow2 virtual size: 1.0G (1073741824 bytes) disk size: 196K cluster_size: 65536 Format specific information: compat: 1.1 lazy refcounts: false If you want prepare the backing chain yourself, you should add "-o backing_fmt=$farmat" options, like "qemu-img create -f qcow2 base.s1 -b base.qcow2 -o backing_fmt=qcow2"
