I believe it would be, I really am just trying to avoid using iSCSI
due to overhead.  I also am struggling to understand XCP a bit I
guess.  Is it really just Xen with VSwitch, Vastsky and a few other
magic bits thrown in, or is it entirely something new that tools you
would normally use with Xen won't work with?  Does it use Vastsky and
VSwitch by default when you set up some systems, or do you have to
configure something special to make use of the switching and storage?


NFS has much more overhead than iSCSI. It also runs on TCP/IP (which is why iSCSI has so much overhead), but you have an NFS server and "forgeign" file system as well.
Best would be to use AOE (if you can't change to Fibre Optic) and then use something like ZFS / EXT4 on the Hypervisors
