OVM 3.3.1: NFS storage is not available during repository creation

Question

Hi, I have OVM Manager  running on a separate machines managing 3 servers running OVM server  in a server pool. One of the server also exports a NFS share that all other machines are able to mount and read/write to. I want to use this NFS share to create a OVM repository but so far unable to get it to work.
From this first screen shot we can see that the NFS file system was successfully added under storage tab and refreshed.

But its is not available when adding a repository as shown below. What can I did to make it show up here.

No luck with CLI either.  Any thoughts?
OVM> create repository name=myrepo fileSystem="share:/" sharepath=myrepo - Configurable attribute by this name can't be found.
== NFS file system refreshed via CLI === 
OVM> refresh fileServer name=share

Actually, OVM, as is with all virtualization servers, is usually only the head on a comprehensive infrastructure. OVM seems  quite easy from the start, but I'd suggest, that you at least skim trough the admin manual, to get some understanding of the conecpts behind it.  OVS thus usually only provides the CPU horse power, but not the storage, unless you only want to setup a single-server setup. If you plan on having a real multi-server setup, then you will need shared storage.
The shared storage for the server pool, as well as the storage repository can be served from the same NFS server without issues. If you want to have a little testbed, then NFS is for you. It lacks some features that OCFS2 benefits from, like thin provisioning, reflinks and sparse files.
If you want to remove the NFS storage, then you'll need to remove any remainders of any OVM object, like storage repositories or server pool filesystems. Unpresent and storage repo and delete it afterwards… Also, I hope that you didn't  create the NFS export directly on the root of the drive, since OVM wants to remove any file on the NFS export and on any root of ony volume there's the lost-found folder, which OVM, naturally, can't remove. Getting rid of such a storage repo can be a bit daunting…
