[ovirt-devel] new storage domain question

Hi, I just found something very interesting. While installing latest ovirt, I've created the shared_storage on my nas1 share folder (NFS). So far, so good. However, when trying to create additional 2 new storage domains, I can only create 1 (which means the shared_storage is 1 and a new one is 2, I cannot create a 3rd storage domain, 4th etc..). When I try, it shows an error (I don't remember which error right now). Why is that? and why this strange (IMHO) shared_storage thing? in a corporate, if I want to set up a virtualized environment, the storage administrator asks me which one I want (NFS, or an iSCSI LUN), do I need one or more, and then I'm adding them as a datastore (in VMWare, for example) and on top of that I'm installing the management software (for example, vCenter). with oVirt method, it will confuse VMware admins. Thanks
