[one-users] Ceph image creation works ... but disk is empty (ONE 4.6 beta)

[Stefan Kooman]

Hi List,

I've setup a 5 node ceph cluster and 2 kvm nodes. Everything is working
fine. Ceph cluster is healthy, etc. I'm able to list images on the
frontend, kvm nodes. Datastore is added succesfully:

However, If I import an image from the marketplace it gets registered
succesfully. But actually the image is empty:

qemu-img info rbd:one/one-9
image: rbd:one/one-9
file format: raw
virtual size: 0 (0 bytes)
disk size: unavailable

Image details:

I've manually created a qemu-image (qemu-img convert -f qcow2 -O raw
debian_squeeze.qcow2 rbd:one/debian2) and made a libvirt xml based on
openenbula default.  That image just works. Everything seems to be in
order, no errors anywhere, but result in empty images nevertheless.
