Greetings,
Description
===========
I'm trying to attach an encrypted volume to a nova instance. Still, I'm facing "libvirt.libvirtError: internal error: unable to execute QEMU command 'blockdev-add': Image is not in qcow2 format" error.
I'm using generic-NFS with luksv1 encryption as a cinder backend.
Steps to reproduce
==================1. Create a nfs encrypted volume
$ cinder list
++--------------------------------------+-----------+-------------------+------+-------------+----------+-------------+
| ID | Status | Name | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+-------------------+------+-------------+----------+-------------+
| 1a1dc33c-5b99-47b3-9619-4542f6ed5ce0 | available | encrypted-volume5 | 1 | LUKS | false | |
+--------------------------------------+-----------+-------------------+------+-------------+----------+-------------+
2. Attach the volume to the instance
$ nova volume-attach 9b595d6f-484c-4b38-9a8e-4d2fafe7bceb 1a1dc33c-5b99-47b3-9619-4542f6ed5ce0
Expected result
===============
Volume attached successfully.
Actual result

Environment
===========
I'm working on NFS encrypted volume support. The main patch is I896f70d204ad103e968ab242ba9045ca984827c4 [1] and it's merged but it's having some bugs so I'm manually using Ic9dae03272cb8401b3bd2be0a817cf2c54457118 on my Devstack (master branch) as well.
