Can I use an NFS share for ephemeral disk storage with Nova only?

I want to use a NFS share (Not Ceph or GlusterFS) to store ephemeral Nova disks (no Cinder). Is there any guide or instructions to set this up? Also, can I use one share for all my compute nodes or do I need a share for each node?

UPDATE
Per your second concern I would recommend follow:-
https://kimizhang.wordpress.com/2013/...

Setup GlusterFS cluster for nova-compute nodes as the most simple solution (not best)

I know that Ceph appears to be a kind of standard for Glance and Cinder back ends in meantime
But setting up Ceph Cluster and tune it to work with nova might be more complicated then Gluster's one at list via my experience
http://docs.openstack.org/ha-guide/st...

 The final conclusion (from myself of course) is :- As far live migration comes into concern you get forced to set up    Ceph or Gluster Clusters to serve as Glance back end.

The first link makes it seem straightforward, will I be able to migrate instances with this method?
