Hi,

In this case, they are format 2. And they are from cloned snapshots.
Exactly like the following:

# rbd ls -l -p volumes
NAME                                                         SIZE
PARENT                                           FMT PROT LOCK
volume-099a6d74-05bd-4f00-a12e-009d60629aa8                 5120M
images/b8bdda90-664b-4906-86d6-dd33735441f2@snap   2

I'm doing an OpenStack boot-from-volume setup.

OK i've never used cloned snapshots so maybe this is the reason.

strange i've never seen this. Which qemu version?

# qemu-x86_64 -version
qemu-x86_64 version 1.0 (qemu-kvm-1.0), Copyright (c) 2003-2008 Fabrice Bellard

that's coming from Ubuntu 12.04 apt repos.

maybe you should try qemu 1.4 there are a LOT of bugfixes. qemu-kvm does not exist anymore it was merged into qemu with 1.3 or 1.4.
