Yup, standard behavior.

Well you've demonstrated that the user "vdsm" can r/w the NFS export 
from the hypervisor.  This is a common source of problems as things like 
selinux and UID/GID mismatches can cause all sorts blockages preventing 
VDSM's ability to r/w the NFS export.

Let's see what VDSM thinks.  From a hypervisor do this...
1. Type "mount"
2. Look for your ISO domain in the returned list.
3. Note the local path to the ISO domain.  It might look something like 
this...
  /rhev/data-center/mnt/oravm3.acbl.net:_isodomain
4. List the directories in it:
   ls /rhev/data-center/mnt/oravm3.acbl.net:_isodomain
5. Notice the returned UUID directory name:
  [root at node ~]# ls  /rhev/data-center/mnt/oravm3.acbl.net:_isodomain
  92cf90c2-3698-48b5-84fd-d8e4f8684549
6. Supply that to the vdsClient command as follows:
   vdsClient -s 0  getFileList  92cf90c2-3698-48b5-84fd-d8e4f8684549

What happens?
