[one-users] opennebula and ceph authentication

[George Kissandrakis]

Bill
I am one step ahead
oneadmin has everything configured and accessed
it can create disk images in ceph. permissions is not the problem

the problem is that oneadmin starts kvm --drive=[..],auth_support=none[..]
and not kvm --drive=[..],auth_support=cephx[..]
and i don't know how to configure that in opennebula
