[Users] add NFS storage domain fails on mount timeout via ovirt

When trying to add an NFS Export domain via oVirt-engine, it fails on 
"Problem while trying to mount target". 
when checking the vdsm.log, it seems that the problem is mount time-out. 

when I tried to manually run the mount command, in the exact same manner 
as vdsm, it indeed failed on Connection timed out after ~3 minutes or so: 

[root at localhost vdsm]# /usr/bin/mount -t nfs -o soft,nosharecache,timeo=600,retrans=6,nfsvers=3 /rhev/data-center/mnt/ 
mount.nfs: Connection timed out 

but - when trying to run the mount command again, with the exact same mount 
source and mount target, but without any additional parameter, it succeeded 
(after ~10 seconds): 
[root at localhost vdsm]# /usr/bin/mount /rhev/data-center/mnt/ 

So I assume that I need to either configure my NFS Export folder differently, 
or create the storage domain with additional parameters (using the "Advanced 
Parameters" section in the GUI dialog or similar). 

any pointers on what exactly should be checked / done?

many thanks in advance.
