I think this might be part of your problem.  The host drops privileges to
vdsm:kvm and needs to work with files which may not be world writable.
Consider changing the above to:

/mnt/pool/ovirt  -alldirs -mapall=36:36 146.164.36.137

Since the vdsm user is always 36 and the kvm group is always 36.

calls.  My first guess is this is a permissions error (although I am not
sure why it would also fail with iscsi).
