[one-users] Shared datastore only to cluster

Hi all,

i'm trying to build a opennebula infrastructure, but i guess i'm missing
something basic about datastores.

Currently i have 3 ubuntu hosts virtualizing several kvm guests. Created
another guest and installed Opennebula 4.2 over a Gentoo in this new guest.
Removed all VMs from the third host, created a cluster in sunstone
interface, added to it this host. For far so good, the host is monitored
and showing available CPU/RAM.

Next step was to "import" a qcow2 image from a stopped guest and use it in
this host. This files and shared across all hosts using ocfs2 over fc luns
(opennebula guest don't actually have access to them).

So, my problem here is:

Can I add this image files to a datastore that only exists in the cluster
hosts? It seems that i can't do this without placing them in the frontend
guest.
