[Openstack] Ceph bootable cinder volume not working in Havana

So I finally got Ceph and cinder bootable volume to work. For those interested on what I had to do. I had to reinstall everything and before I installed the nova components I installed the latest ceph client emperor. Now in the nova install there are some ceph components that it will install. If you now install nova it will error out about some broken dependency and ceph-libs. Do not install ceph-libs, all you need to install is qemu-common. If you do a yum install it will try to install ceph-libs so do not install via yum. Download the rpm and install the rpm of qemu-common with the --nodeps option. Then run everything else. Do everything in the ceph documentation and make sure the client.volumes or whatever cinder user name you call it has access to both the glance and cinder pools you make. Done!

I have noticed a similar problem.
I have 2 different pools:
images and volumes and both use the same ceph.user keyring.
I can create a volume from an image but if I try to cause the image to copy as part of an instance start up things. fail.
I wonder if the problem is using 2 different pools?
