Other than these limitations, everything works. You can create instances and attach RBD disks. It also supports cephx authorization, so no problem there!
I found a bug in libvirt under Ubuntu 12.04. In short, the base64 encoding/decoding inside libvirt is broken due to a third party library.

What do you need to run this patch? - A Ceph cluster - libvirt with RBD storage pool support (>0.9.12)
I recommend running 0.9.13 (just got out) since it contains RBD support. But there is a bug if you're not running with cephx, this just got fixed: http://libvirt.org/git/?p=libvirt.git;a=commit;h=ccb94785007d33365d49dd566e194eb0a022148d
In a couple of weeks libvirt 0.9.14 will be released and that will contain everything you need and will probably fix the base64/secret problem as well.
- Modified libvirt-java bindings (jar is in the patch)
Tomorrow there will be a release of libvirt-java 0.4.8 which will contain everything you need. No more need for a homebrew version of the libvirt Java bindings, we can use the upstream ones!

- Qemu with RBD support (>0.14) - A extra field "user_info" in the storage pool table, see the SQL change in the patch You can fetch the code on my Github account [3].
Not true anymore, I'm now pushing to the "rbd" feature branch at the Apache CloudStack repository.
Warning: I'll be rebasing against the master branch regularly, so be aware of git pull not always working nicely. I'd like to see this code reviewed while I'm working on the latest stuff and getting all the patches upstream in other projects (mainly the libvirt Java bindings).
Like said, the libvirt Java bindings have gone upstream and that should be settled by tomorrow.
