I'd suggest you consider one of the following options:
* export (possibly read only) the file you want to the domU using NFS
* export the guest's filesystem using NFS and then copy files onto it
* set up SSH keys so that you can simply scp files into the guest
* boot the guest from NFS entirely
* use a cluster filesystem

There are probably more options too.  I would think that setting up ssh keys 
and then using scp would be the simplest way of doing things if you have 
network access.
