I updated document about zone-wide primary storage support for 4.1(https://cwiki.apache.org/confluence/display/CLOUDSTACK/Zone-wide+primary+storage+target): limit the scope for only KVM + zone-wide NFS storage. And I think Ceph should be doable also, as the changes I made are not related to a particular type of storage, as long as the hypervisor supports it. Any comment?
