[ClusterLabs] VirtualDomain as resources and OCFS2

Hi,

i'm establishing a cluster with virtual guests as resources which should reside in a raw files on OCFS2 formatted logical volumes.
My first idea was to create for each VirtualDomain its own logical volume, i thought that would be well-structured. 
But now i realize that my cluster configuration gets confusing. E.g. i need for each OCFS2 Volume a resource, which must be cloned and which has an order with its respective guest. I'm having about 10 Virtual Domains. 10 VirtualDomain resources, 10 clones, 10 orders. Confusing.
Now i'm thinking of one Logical Volume for all VirtualDomains. Then the cluster configuration would be more overseeable. Just one OCFS2 resource, just one clone, just one order. 
Is there any reason which contradicts to the use of only one LV and one OCFS2 resource for several VirtualDomains ?

Thanks.


Bernd
