OK. nb. block level devices such as NBD, iSCSI and friends are fine for a "read many, write exclusive" setup - e.g. multiple domains mounting a device and reading from it, but they must all unmount in order for a single writer to modify the contents. This works without any fuss, using a normal non-cluster filesystem. For some scenarios, this suffices. Otherwise, good luck with your setup. IIRC, OpenFiler offer Xen-enabled appliance downloads so that should serve your purposes.
