Was this problem ever resolved? I'm having the identical issue right now (perhaps because I am following Sebastien's guide [0]). I found this question raised on LP [1], but no helpful responses, and no linked bug. I can confirm that I can attach an RBD instance manually through virsh, no problem. So it is not a libvirt thing. It sure appears to be a faulty disk attachment definition from OpenStack.
I'm running the latest packages on Ubuntu 12.04 for OpensStack (essex) and Ceph (argonaut). I can confirm when using nova volume-attach it does not matter what device you pick, dev/vdb, dev/vdf, whatever. Always fails. /dev/vdb manually works great.
