This seems to be related to https://review.openstack.org/#/c/453341/7/cinder/image/image_utils.py . This change is adding "-f src_format" to the qemu-img convert command-line, and that fails when the image type is "ami", because this is not a supported image type for qemu-img.
An easy way to reproduce this error is:
1- Upload an ami image (+kernel/ramdisk) to Glance.
2- Try to create an instance, booting from volume, using that image.
