[Users] Issue with Export/NFS storage domain

[Georg Troxler]

In ovirt 3.2 with the AllInOne plugin there seems to be an error when I 
add new Export/NFS Domain:

I used the following parameters:

Name: export-domain
Data Center: local_datacenter
Domain Function / Storage Type: Export / NFS
Use Host: local_host
Export Path: 192.168.10.105:/mnt/datasstore/vm-storage/export

It looks as if the subsystem expects a mount point at 
'/rhev/data-center/mnt/192.168.10.105:_mnt_datasstore_vm-storage_export'. If 
I create the mount-point manually, change owner and permission the 
operation still fails.

Unfortunately I could not find specific information regarding the 
creation of an Export store other than the documentation on how to 
create an NFS store. Maybe I am missing something?
