Yes, thats the way I do it.
If you add the exports using the UI you don't get the right lines in
/etc/exports but if you enable ssh access you can edit the file and than do:
mkdir -p /volume1/ovirt/{he|data}
chown -R 36:36 /volume1/ovirt
install oVirt using the nfs path your.nas:/volume1/ovirt/he
That should work.
Greetings,
