How does the VM access the shared storage? Lets say you use Iscsi.
For the root partition to mount an ocfs2 volume, you will need to log in 
to the iscsi target and then  mount the ocfs2 volume all this handled by 
the initrd. This may be difficult to accomplish. I would start with  
getting a iscsi target (ext3 )  root partition working , then  work on 
ocfs2.

Once again, try mounting the root partition on boot only using iscsi.  
This is easier as you avoid creating a custom initrd.
