Ahh. Now that is a fish of a different colour.
I was trying vol-upload and vol-download and your explanation makes it
clear why they would not work.
I wonder if sticking an rdb-fuse mount under libvirt to allow copy in
and out functions to work would make sense.
I will back up and try to see if my problems have gone away on the
openstack side.
I also noticed that virt-manager would not display the rbd pool while
the ceph documents on the web clearly were using virt-manager to check
that the config was correct.
Oh well.

I have a ceph pool defined.
I can create and destroy volumes
but I cannot read or write them.
I get the following error in libvirt log.

Which command did you use? Since this is a problem in libvirt which I
already encountered a long time ago.
libvirt still assumes all volumes are regular files or block devices
and it simply does a fopen() and that obviously fails.
This should be handled by the backing storage pool, but that's not how
libvirt currently works.
