This is the kvm command our libvirt is trying to do, from
/var/log/libvirt/qemu/one-58.log
Clearly it is an authentication error, the only question is
what and why.. we have made the client.libvirt secret
as directed at
http://docs.opennebula.org/4.8/administration/storage/ceph_ds.html
The example there suggests to set CEPH_USER="libvirt"
but I don't have a "libvirt" user defined on my system (most RHEL6/SL6
systems don't.). Should we use a different user?

Does anyone have a working Ceph datastore that would
be willing to send me a copy of what the deployment.0 of
your successfully-launched Ceph VM looks like? Likewise
a ps -ef of the corresponding running KVM process?
We are getting close to being able to launch a virtual machine from
Ceph but it is still not quite clear what libvirt is doing
under the covers to talk to rbd, and if it can be tested manually.

The first and most obvious problem below was that we were running an
old version of qemu-img and qemu-kvm that ships with RHEL6/Centos6/SL6
that doesn't support the "rbd" format. We were able to find
a modified version that the Ceph people had back-ported and now
we can import an image into the datastore and have
gotten as far to getting a deployment.0 written on the hypervisor.
It can't contact Ceph as yet, is getting connection refused but
we think that is an authentication issue.
http://ceph.com/packages/qemu-kvm/redhat/x86_64/
is where these packages for 6.2 live.
Hopefully this all gets easier pretty soon now that RedHat has bought Ceph
and all the right packages will be in RHEL7. Or will they be only
proprietarily available in Redhat Enterprise Virtualization? Has anyone
tried yet?
