[one-users] Opennebula, Ceph and Libvirt 0.10.2

[Jaime Melis]

Hi Michael,

yes, this is known limitation of the current Ceph drivers. We are still
considering it to do it before OpenNebula 4.4 is out.

However, there's something I don't fully understand, it should work with
auth_supported = none, and *not* with auth_supported = cephx, is this what
you meant?

cheers,
Jaime
