If you want all of the i/o fencing capabilities (etc) of GFS, you'll
have to use the pciback/etc Xen stuff to give the HBA to the domU.
However, simply for GFS to work, I believe all you'd need to do is pass
the SAN LUN down to the domU via your Xen config (phy:/dev/sdX,...).
GFS works based on the fact that it's a SCSI disk, not so much on the
concept that it's "a SAN."

(Disclaimer: I haven't actually done this, it's just what seems
logical. :))
