Please read xenstore-chmod(1). This is not the correct syntax. You need
"b" (both) not "rw".

Did you actualy load those modular drivers which you listed above? e.g.
modprobe xen-gntdev, xen-gntalloc and xen-evtchn.

Did you install the .ko files in domU in the appropriate place?

Do you have udev installed and working?

Do those drivers appear in /proc/misc?

/proc/xen != /dev/xen.
