Yes, it made a difference:

root@ceph-node1:~# qemu-img info rbd:vm_disks/box1_disk1
image: rbd:vm_disks/box1_disk1
file format: raw
virtual size: 10G (10737418240 bytes)
disk size: unavailable



I'm not sure if qemu-img guessed the format correctly.
Does the above output seem normal?


Thanks!

Hi,

Try leaving out "-f rbd" from the command - I have seen that make a 
difference before.
