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 On Wed, Oct 30, 2013 at 11:24 AM, Michael <[email protected]>wrote: > Hi, > > I'm having an issue with a newly added CentOS node to opennebula, on my > Ubuntu nodes the default libvirt is 9.X and seems to work fine, the ceph > docs <http://ceph.com/docs/master/rbd/libvirt/> suggest things have been > changing libvirt late 9.X which might now be causing a problem on my new > 10.2 nodes. > > It's essentially the same issue as > http://lists.opennebula.org/pipermail/users-opennebula.org/2013-June/023323.htmlthat > never got answered/resolved.
