Do this on the nfs-server. Basically what happens in the background is your hv 
is making a connection to the NFS server as user kvm (36)/group vdsm(36) in 
order to obtain the iso information. If the NFS server doesn't have that user 
or the permissions to read the directory it will fail.

Note that the engine itself doesn't need to be able to connect to the nfs-
server, its the HV (the vdsm process to be exact) that makes the connection.  
The engine just tells the vdsm process what it wants done. This is also why 
when the engine is down your VMs will be unaffected as its actually vdsm 
controlling stuff.
