qemu 2.9 returns an extra layer in the backing data if a block job is active. Add a test case to see whether our code properly detects and ignores such layer. The test data was prepared by creating a backing chain of qcow2 images (with qemu-img and with libvirt's snapshot feature). One of the layers was then merged back by doing a block-commit: virsh blockcommit VM hda --top /var/lib/libvirt/images/b and then a block-copy job was started and kept in synchronized phase: virsh blockcopy VM hda /tmp/tgt.img --transient job Reviewed-by: Eric Blake <eblake@redhat.com>
