Hi,<br>
<br>
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 <a href="http://ceph.com/docs/master/rbd/libvirt/" target="_blank">ceph docs</a>
suggest things have been changing libvirt late 9.X which might now
be causing a problem on my new 10.2 nodes.<br>
<br>
It's essentially the same issue as <a href="http://lists.opennebula.org/pipermail/users-opennebula.org/2013-June/023323.html" target="_blank">http://lists.opennebula.org/pipermail/users-opennebula.org/2013-June/023323.html</a>
that never got answered/resolved. The VM fails to build on a disk
mounting error which looks like it might be resolvable by switching
the command used by Opennebula from "auth_supported=none" to
"auth_supported=cephx" but I've tried looking through as many of the
opennebula files as I can think might be relevant <br>
but can't find where this could be changed.<br>
<br>
