Kilo Nova/Cinder Version 1:2015.1.2-0ubuntu2~cloud0
Ceph Version 0.94.5-1trusty
Apologies, this issue crosses multiple packages, Nova/Cinder/CEPH, I am
fairly confident this issue stems from nova/libvirt/driver.py but I lack
the necessary knowledge to dig much further.

Steps to reproduce this error:
1) Create Image with metadata, as recommended by :
http://docs.ceph.com/docs/master/rbd/rbd-openstack/
hw_scsi_model=virtio-scsi: add the virtio-scsi controller and get better performance and support for discard operation
hw_disk_bus=scsi: connect every cinder block devices to that controller
hw_qemu_guest_agent=yes: enable the QEMU guest agent
os_require_quiesce=yes: send fs-freeze/thaw calls through the QEMU guest agent
2) Upload image with Qemu Guest Agent installed.
3) Create an instance with a Cinder Volume.
4) Snapshot that instance whilst the instance is running.
Note: A forced snapshot of the volume through cinder will succeed, as
will the snapshot if the require_quiesce is disabled. This may result in
an inconsistent snapshot.
